The height is 26 miles. Multiply that by 2 which gets 52 and then subtract that from 84. That gives you 32 which means the sum of the lengths is 32/2 which is 16 miles
0 solutions move the x to one side, and the numbers to the other. 12x (-12x) + 32 (-32)= 12 (-12x) - 7 (-32) 12x - 12x = -7 - 32 0 = -39 0 ≠ -39 ∴ you have 0 solutions hope this helps
