look at all of this math. do it all or something for 50 points each ig
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)
x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]

12x-18y*-90
Simplifying
12x + -18 = 90
Reorder the terms:
-18 + 12x = 90
Solving
-18 + 12x = 90
Solving for variable 'x'.
████████████████████████████████████████████
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 12x = 90 + 18
Combine like terms:
-18 + 18 = 0
0 + 12x = 90 + 18
12x = 90 + 18
Combine like terms:
90 + 18 = 108
12x = 108
Divide each side by '12'.
x = 9
Hence,
x = 9

Michelle ordered 200 T-shirts to sell at the school carnival. She paid $2.80 per shirt, plus 5% of the total order for shipping. When she sells each T-shirt at the carnival, she adds 150% markup to the total price she paid for the shirt (including the cost of shipping). What is the selling price of each T-shirt? help i only have 10 points but plz help
Answer: 4.18$ or 4.19$ per shirt (I’m not entirely sure my answer is correct but do what you must with this info)
Step-by-step explanation: 200 times 2.80 is 560,
5% of 560 is 588,
150% of 588 is 882,
and then 882 divided by 200 is 4.18 (or 4.19)
PLsss help nobody is helping me :(
This is graphing and if you only want points ill report
Answer:
is the answer t = $2.00 ?????
Answer: The variables are the Cost of the item, and the Total cost.
The other cost, the shipping is given here: $2. So that is not really a variable.
You can use almost any letters you'd like. I'm using C for the item's cost, and T for the total cost in this equation:
C + 2 = T
This question seems to imply that only one item is in the order
Step-by-step explanation:
There may be other ways to do this, if multiple items are ordered.
The variables are the Cost of the item-- and how Many items are purchased.
The Total is also a variable that depends on how many and the cost of the items.
The other cost, the shipping might be a variable in other questions (not here) here: S could be a variable if it is a percentage ot the cost.
You can use almost any letters you'd like. I'm using C for the item's cost, M for the number of items, S for variable shipping, and T for the total cost in this equation:
M×C + S = T
For the exercises below, find the growth factor and the y-intercept of the equation's graph.

Answer:
2) M(2, -4), N(-2, 4)
Step-by-step explanation:
Point L is at (-2, -4). When it is reflected across the y-axis, the x value will turn into its opposite. This means point M is at (2, -4). This same logic applies to reflecting across the x-axis only this time the y value will turn into its opposite. Therefore, point N is at (-2, 4).

Hunter bought a cell phone for $159 and 6% sale tax was added at the register. Hunter gave the cashier nine $20 bills, how much change should he receive?
Answer:
Step-by-step explanation:
So in order to solve this you would multiply 159 by 6% and get 9.54 so therefore you add the 9.54 to 159 and get 168.24 Then you add together all the bills which is 180 and subtract 180- 168.24 which equals 11.76 so the answer to your question is that Hunter shall received $11.76 in change.

Answer these questions about killer whales:
What do killer whales look like? Be very specific, colors, size, length, spots, stripes, camouflage...etc.
What are some facts about killer whales? List at least 5.
I will give brainliest, thanks, friend request, and 5 stars to the best answer.
Answer:
Adult male killer whales are larger overall than their female counterpart including features such as pectoral flippers, dorsal fins, tail flukes, and girth. The largest recorded male killer whale was 9.8 m (32 ft.) in length and weighed 10,000 kg (22,000 lbs.) The largest recorded female was 8.5 m (28 ft.) and weighed 7,500 kg (16,500 lbs.). Data from Icelandic killer whales (North Atlantic type 1) indicate that an average-size male is about 5.8 to 6.7 m (19 to 22 ft.) long, while females averaged 4.9 to 5.8 m (16 to 19 ft.) long. Killer whale sizes vary significantly between different ecotypes.
Male Antarctic type A killer whales can reach lengths of 9.2 m (30 ft.) making them the largest known killer whales. The smallest killer whale ecotype is the Antarctic type C killer whales in which adult females average 5.2 m (17 ft.) and adult males average 5.6 m (18 ft.) in length and can reach a maximum of 6.1 m (20 ft.). At SeaWorld, average size for adult males is 6.6 m (21.7 ft.) Two of the largest adult male killer whales at SeaWorld weigh 4,340 kg (9,570 lbs.) and 5,380 kg (11,860 lbs.).
At SeaWorld, average size for females is 5.5 m (18 ft.) and 2,442 kg. (5,384 lbs.) SeaWorld's adult female whales range in weight from 2,313 kg (5,100 lbs.) to 3,719 kg (8,200 lbs.). The general body shape of a killer whale is roughly cylindrical but tapering at both ends. This characteristic fusiform shape is quite energy efficient for swimming. Killer whales are black and white, with a gray patch called a "saddle" or a "cape" on the back, just behind the dorsal fin. A killer whale's forelimbs are adapted for swimming. A killer whales uses its rounded, paddlelike pectoral flippers to steer and, with the help of the flukes, to stop. A killer whale's pectoral flipper contains 5 digits much like the fingers on a human hand. Each lobe of the two-lobed tail is called a fluke. Flukes are flat pads of tough, dense, fibrous connective tissue, completely without bone or cartilage. Like the flukes, the dorsal fin is made of dense, fibrous connective tissue, without bones or cartilage. A killer whale has an indistinct rostrum (snout-like projection).
A single blowhole on top of the head is covered by a muscular flap. A killer whale breathes through its blowhole. The blowhole is relaxed in a closed position, and the flap provides a water-tight seal. To open its blowhole, a killer whale contracts the muscular flap.
A killer whale's eyes are on each side of its head, just behind and above the corner of its mouth, and in front of its white eyespot.
A killer whale's large teeth are conical and interlocking. Toothed whales have only one set of teeth; they are not replaced once lost. The number of teeth varies among individuals. There are usually 10 to 14 teeth on each side of each jaw (40 to 56 teeth total). A killer whale's blubber layer lies beneath the dermis and measures from 7.6 to 10 cm (3 to 4 in.) thick. Blubber is a layer of fat reinforced by collagen and elastic fibers. In general, blubber has a number of important functions: A killer whale's dermis (skin) is smooth. The outer layer continually and rapidly renews itself, and the old skin sloughs off. The increased skin cell turnover increases swimming efficiency by creating a smooth body surface which reduces drag.
Facts:
1) The name killer whale derives from their original name ‘whale killers’ given to them by sailors who saw them hunting whales. Over time, the name eventually switched around. The name ‘orca‘ comes from their Latin species name Orcinus orca, where orcinus translates to mean ‘Kingdom of the dead’.
2. Despite their name, killer whales are actually a dolphin – the largest species of oceanic dolphin!
3.Whilst they can and do eat prey such as finfish and marine mammals, New Zealand orca have become specialised at hunting sharks and rays. They can often be seen up around rocky reefs and in the shallows of beaches while they are hunting.
4.The average life span of an orca is not too dissimilar to a human, at 50-80 years for females and slightly less for males at 29-60 years.
5.Orca can be seen in every ocean on the earth. They are one of the most successful marine mammals in terms of range.
