3x+14=2+5x-20
3x+14=5x-18
-5x -5x
-2x+14=-18
-14 -14
-2x=-32
Divide that -32 with -2
And the answer is x=16.
This should be the answer
72 = 1/2 (16x) because the area of a triangle is 1/2 (bh) and the height is x and the base is 16 and the area = 72 so solve for x to get base.
<span>x = 3√2 is what i got</span>

to calculate the midpoint use the midpoint formula
midpoint = [
(9 + 0),
(- 1 + 7)] = (
