A(X)=(3x-2)^2-(2x-3)^2
Answer:
5(x - 1)(x + 1)
Step-by-step explanation:
A(x) = (3x - 2)² - (2x - 3)² = (3x - 2 + 2x - 3)[3x - 2 - (2x - 3)] = 5(x - 1)(x + 1)
What is the equation of the line parallel to line l that passes through point (3,3)
Answer:
Step-by-step explanation:
Let the equation if the line be y = mx + c
since the line is parallel to y = (smt-your question isn't complete), their gradients/slope must be the same (aka m = __)
sub (3, 3):
3 = __(3) + c
c = __
therefore, the equation of the line is y = __x + __

If a 30-year-old male exercises 2 hours per week, what would you
expect his resting heart rate to be?
Answer:
(71) I believe
Step-by-step explanation:
hope this helps :3
if it did pls mark brainliest
sorry if im wrong
Answer:
Approximately 72 bpm.
Step-by-step explanation:
In order to find the expected heart rate you need to look at the x-axis on the graph. Since the male exercises 2 hours a week, use that value for x and find where x = 2 lies on the line. In this graph, the line goes through x = 2 at the same time it goes through y = 72. Since the y-axis represents the resting heart rate, we now know that if a 30 year-old male exercises for 2 hours a week, his resting heart rate will be around 72 bpm(beats per minute).
I hope this helps :)
Solve the following absolute value equation in the work space. Be sure to circle
your answer(s).
|3t +3|=18
Answer: so the answer t= 5, -7
3t + 3 = 18
( we subtract 3 from both sides)
3t + 3 = 18
- 3 -3
3t = 15
( then we divide both sides by 3 )
3t/3 = 15/3
t = 5
(and this is the negative part, we do most of the same steps as teh last one)
3t + 3 = -18
- 3 -3
3t = -21
3t/ 3 = -21/ 3
t = -7

A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT
Answer:
The inner surface area of a hemispherical bowl will be: 1923.25 cm²
Step-by-step explanation:
Given
d = 35 cm
as
[tex]r=\frac{d}{2}[/tex]
[tex]=\frac{35}{2}[/tex]
[tex]= 17.5[/tex] cm
The inner surface area of a hemispherical bowl = 2πr²
[tex]=2\times 3.14\times \left(17.5\right)^2[/tex]
[tex]=6.28\:\times \:17.5^2[/tex]
[tex]=1923.25[/tex]
Hence, the inner surface area of a hemispherical bowl will be: 1923.25 cm²

4 Abi is going to buy ingredients to make 65 hot chocolate drinks.
She needs 12 g of chocolate powder and 5 marshmallows to make each drink
Abi can buy
chocolate powder in 250 g jars at £2.99 per jar
marshmallows in bags of 120 marshmallows at £1.45 per bag
Work out the total cost of the chocolate powder and the marshmallows she needs to buy.
Answer:
To make 65 chocolate drinks, she needs:
12 g of chocolate powder and 5 marshmallows per drink.
Then she needs:
12g*65 = 780 grams of chocolate powder.
We know that the chocolate powder comes in jars of 250g, such that each one costs £2.99
If she buys 3 jars, she will have: 3*250g = 750g
So she will not have enough, then she needs to buy 4 jars.
Then in chocolate powder, she will pay 4 times £2.99 = £11.96
And for marshmallows, she needs:
65*5 = 325 in total.
Marshmallows come in bags of 120, then the number of packs that Abi needs to buy is:
325/120 = 2.7
That should be rounded up (because she can not buy a 0.7 of a bag)
Then she needs 3 bags, and each bag costs £1.45
Then the total cost in marshmallows is 3*£1.45 = £4.35
Grayson has 4 small photo albums and 6 large photo albums. Each small album can hold up
to 112 photographs. Each large album can hold up to 184 photographs. How many photos can
Grayson keep in the albums? Enter your answer in the box.
Answer:
1552 Photos
Step-by-step explanation:
I relabeled the albums as SP (Small album) and LA (Large album)
1 la holds 184
1 sp holds 112
112 • 4 = 448
184 • 6 = 1,104
448 + 1,104 = 1552
A store buys 11 sweaters for $154 and sells them for $363. How much profit does the store make per sweater?
Answer:
they make $19 dollars in profit per sweater
Step-by-step explanation
154/11 is 14. This means that they paid $14 dollars per sweater.
363/11 is 33, meaning that they sold each sweater for $33.
$33 - $14 is $19, thus they made $19 dollars per sweater.
(I could be wrong, though. I tend to make dumb and simple mistakes of simple math, lol)
Answer:
19
Step-by-step explanation:
First Find the difference of the two amounts.
Profit = Sale - Cost
Profit = 363 - 154
Gross Profit = 209
Each sweater sold brings in a profit of 209 / 11 = 19 dollars

You roll a standard dice two times. What is the probability of getting a 6
on the first roll, then an even number on the second roll?
Answer:
4 out of 12 chance.
Step-by-step explanation:
So its a 1 out of 6 chance for the first die, and a 3 out of 6 chance on the second die, so a 4 out of 12 chance of what was said to happen.
First die:
You want to roll a 6. There is one number on each side of the die, and there are 6 sides. Since you can only get a side with 6 once, you have a 1 out of 6 chance of landing a 6.
Second die:
You want to roll an even number. There are 3 even numbers on the die (2, 4, and 6), and there are 6 sides, with the other 3 sides being odd (1, 3, and 5). Since you can only get a side that is even three times, you have a 3 out of 6 chance of landing an even number (2, 4, or 6).
Combine these probabilities together, and you result in a 4 out of 12 chance of getting the requirements. The 4 comes from adding the chance of getting a 1 and 3 even numbers, and the 12 comes from adding the 2 6's (since two dices would result in 12 sides).

In this figure, DC is parallel to AB. angle DCA is 3x+14, angle ACB is 10x+12, and angle CAB is 5x-2. Find the degrees in angle CBA.
Answer:
Angle CBA = 50 degrees
Step-by-step explanation:
Known Information:
DC is parallel to ABAngles DCA and CAB are equal (they are alternate interior angles)Angles CAB + ACB + CBA = 180°Calculations:
[tex]3x + 14 = 5x - 2[/tex][tex]16 = 2x[/tex] [tex]x = 8[/tex][tex]180 - CAB - ACB = CBA[/tex][tex]180 - [ 5(8) - 2] - [ 10(8) + 12] = CBA[/tex][tex]100- [38] - [92] = CAB[/tex][tex]CBA = 50[/tex]The measure of the angle CBA is 50 degrees if DC is parallel to AB. angle DCA is 3x+14.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have:
DC is parallel to AB. angle DCA is 3x+14, angle ACB is 10x+12, and angle CAB is 5x-2.
The equation can be framed:
3x + 14 = 5x - 2
x = 8
Angle CBA = 180 - (Angle CAB - Angle ACB)
Angle CBA = 180 - [5(8)-2+10(8)+12]
Angle CBA = 180 - [40-2+80+12]
Angle CBA = 180 - [40-2+80+12]
Angle CBA = 50
Thus, the measure of the angle CBA is 50 degrees if DC is parallel to AB. angle DCA is 3x+14.

4. The perimeter of a rectangle is 56 centimeters. The length of the rectangle is 2 centimeters more than
the width. Find the dimensions of the rectangle. (Hint: P = 21 + 2w)
I
Answer:
The rectangle has a length of 15 cm and a width of 13 cm
Step-by-step explanation:
Let w represent the width of the rectangle, and let w + 2 represent the length of the rectangle.
Use the perimeter formula, P = 2l + 2w, and plug in the perimeter and w + 2:
P = 2l + 2w
56 = 2(w + 2) + 2w
Simplify and solve for w:
56 = 2w + 4 + 2w
56 = 4w + 4
52 = 4w
13 = w
Then, add 2 to this to find the length:
13 + 2
= 15
So, the rectangle has a length of 15 cm and a width of 13 cm.

Lucy's dog lost 6 pounds. How much weight does her dog need to gain in order to have a net change of 0 pounds?
Answer:
Lucy's dog needs to gain 6 pounds.
Step-by-step explanation:
Lucy's dog lost 6 pounds so the dog will have to gain 6 pounds.
The Dog need to gain 6 pounds for net change of zero pounds.
We have Lucy's whose dog lost 6 pounds.
We have to find out how much weight does her dog need to gain in order to have a net change of 0 pounds.
If you have 'x' toffees and you lost 'y' toffees, then how many toffees you have to buy to recover the lost toffees?Number of toffees left after loosing 'y' toffees = x - y
The number of toffees to buy = x - (x - y) = x - x + y = y
A/Q -
Let the Dog's initial weight be - W
After loosing 6 pounds, the weight will be - W - 6
For a net change of zero pounds, he needs to add = W - (W - 6) = W - W + 6 = 6 Pounds.
Hence, he need to gain 6 pounds for net change of zero pounds.
