Hello from MrBillDoesMath!
Answer: 7/8 * (145) ^ (1/2)
Discussion:
The distance from (-4,5) to (-3, -7) is
the square root of (-4 - (-3))^2 + (5 - (-7))^2 or
the square root of (-4 +3)^2 + (5+7)^2 or
the square root of (-1)^2 + (12)^2 or the
the square root of 1 + 144 = 145
7/8 of this distance is 7/8 * (145) ^ (1/2)
where ^(1/2) indicates the square root of the quantity (145 in this case)
