Question

If UW = 9x - 9, what is UW in units?
5
6
30
36

Answer 1

The answer is 36 Uw in units .

Answer 2

Answer: UW is 36 units long

Step-by-step explanation:
UW is composed of UV and VW, which we have values for. So, let’s make an equation.

(2x - 4) + (4x + 10) = 9x - 9

Solve the left side

6x + 6 = 9x - 9

Subtract 6 from both sides

6x = 9x - 15

Subtract 9x from both sides

-3x = -15

Divide both sides by -3

x = 5

Plug 5 into the equation for UW.

9(5) - 9

45 - 9

36
