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
