m = - 1
Step-by-step explanation:
Given
- 9m - 86 = - 75 + 2m ( subtract 2m from both sides )
- 11m - 86 = - 75 ( add 86 to both sides )
- 11m = 11 ( divide both sides by - 11 )
m = - 1

x = 1500
Step-by-step explanation:
The right triangles are all similar, so the ratio of hypotenuse to short leg is the same for all.
x/900 = (1600+900)/x
x^2 = 900(2500) . . . . . . cross multiply
x = 30(50) . . . . . . . . . . . take the square root
x = 1500
