1) A square has a side length of 10 inches. What is the perimeter?

antiseptic1488 [7]

Answer:

1) 40

2)9x-12

3)42

Step-by-step explanation:

1) A square has 4 sides, and if one side's length is 10, the perimeter (distance around the square) is 10 times 4=40

2) Simply add these values together to get 9x-12

3) Plug in 6 as x in 9x-12. (6*9)-12=54-12=42

Solve for x. 25 - 3x = -5(1 - x) - 2x

grandymaker [24]

Answer:

$x = 5$

Step-by-step explanation:

25 - 3x = -5(1 - x) - 2x

We have to first get rid of the parenthesis:

$-5 * 1$ ==> -5

$-5 * -x$ ==> 5x

So now you should have:

25 - 3x = -5 + 5x - 2x

Combine like terms:

25 - 3x = -5 + 5x - 2x

25 - 3x = -5 + 3x

Add 3x to both sides:

25 - 3x = -5 + 3x

+ 3x = + 3x

And you should have:

25 = -5 + 6x

Add 5 to both sides:

25 = -5 + 6x

+5 = +5

30 = 6x

Divide 6 to both sides:

$\frac{30}{6}$ = $\frac{6x}{6}$

5 = x

Explain how to find the distance between two integers using the difference

jek_recluse [69]

When we want to find the distance between two integers using the difference, the best way is to plot them on number line. And then count distance between them. For example -3 and -1. But distance can not be negative.
