What are 3 math equations for x=-3

Multiply both sides by any number you want. I'll pick 2

x = -3 turns into 2x = -6 after doing so

Add anything you want to both sides. I'll pick 7

x = -3 turns into x+7 = 4 after doing so

you can do a combination of both multiplication and addition, as long as you do the same thing to both sides. First I'll do multiplication. I'm going to multiply both sides by 2 first

x = -3 turns into 2x = -6

then I'm going to add 7 to both sides

2x = -6 turns into 2x+7 = 1

If you were to solve 2x+7 = -1, then you'd get to x = -3 again

As a check, replace x with -3 and we have...

2x+7 = 1

2(-3)+7 = 1

-6+7 = 1

1 = 1

we get a true statement, which helps confirm we have the right equation.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
