Expand the following:
a) x(x + 6)
b) x(5x - 1)
c) 3x(6x + 5)
d) 4x(2x – 3y)​

Answer:

B) 5 Rows and 8 Columns

Step-by-step explanation:

First you take the information from the question to know that C is wrong. This is because It has only 2 desks in rows and the question asks for 4 desks in rows and columns. Next you know that you have 40 desks so the two numbers need to multiply to 40. This makes A and D wrong, leaving your answer as B.

Answer:

C. 5/24

Step-by-step explanation:

John = 3/8

Tim = 1/3

Kevon = ?

---------------------------------

3/8 = 0.375

1/3 = 0.333

0.375 + 0.333 = 0.708

0.292 is left

---------------------------------

5/8 = 0.625 - wrong

9/24 = 0.375 - wrong

5/24 = 0.208333 = 0.293

10/24 = 0.416667 - wrong

Answer:

each balloon costs 1$ and each banner costs 3$

Step-by-step explanation:

The costs of each balloon and banner are $1 and $3 respectively.

A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

Given that, you buy 1 balloon and 1 banner for $4. your friend buys 3 balloons and 2 banners for $9.

Let x represents balloons and y represents banners.

Establishing the equations,

x+y = 4

x = 4 - y......(i)

3x + 2y = 9...(ii)

Put eq(i) in eq(ii)

3(4 - y) + 2y = 9

12 - 3y + 2y = 9

y = 3

Put y = 3 in eq(i)

x = 4-3

x = 1

Hence, the costs of each balloon and banner are $1 and $3 respectively.

ABC dilated

Step-by-step explanation:

Given

Triangles ABC and DEF

Required

Determine the scale of dilation

First, we pick a side on ABC

[tex]AB = 6[/tex]

Pick a corresponding side on DEF

[tex]DE = 3[/tex]

The scale factor is then calculated as:

[tex]Scale\ Factor = \frac{DE}{AB}[/tex]

[tex]Scale\ Factor = \frac{1}{2}[/tex]

i.e. ABC was dilated by 1/2

Answer:

x=16

Step-by-step explanation:

the remaining angle for thw triangle is found by subtracting the already shown angles from 180 (the angle some of a triangle) which happens to be 96 to get 84 but now you need to subtract 84 from 180 to find the angle on the other side of line because lines have a total angle measurement of 180 but we already kbow what this get's us because it's 96 now we devide 96 by 6 to get 16 our answer.

Answer:

22.67 cm^2

Step-by-step explanation:

The computation of the area of the rectangle is shown below:

As we know that

Area of the rectangle = Length × breadth

Here we assume the length be 7.08 cm

Or breadth be 3.2 cm

Or if we assume them inverse like length be 7.08 cm and breadth be 3.2 cm

SO the area of the rectangle is

= 7.08 cm × 3.2 cm

= 22.67 cm^2

In the both cases the answer would be the same

Answer:

-18x + 28

Step-by-step explanation:

2x-7-5(4x-7)

1. Distributive Property

2x - 7 - 5*4x - 5*-7 ( 2 negatives make a positive)

2x - 7 - 20x + 35

2. Combine like terms

2x - 7 - 20x + 35

-18x + 28

Answer:

D (-2,6)

x=y-8;5x+y=-4

Step: Solve x=y−8for x:

Step: Substitute y−8 for x in 5x+y=−4:

5x+y=−4

5(y−8)+y=−4

6y−40=−4(Simplify both sides of the equation)

6y−40+40=−4+40(Add 40 to both sides)

6y=36

6y /6 = 36/ 6  (Divide both sides by 6)

y=6

Step: Substitute6foryinx=y−8:

x=y−8

x=6−8

x=−2 (Simplify both sides of the equation)

x=−2 and y=6
