If you mean m^2 -8m +15 then it equals (m -3)(m -5) when factored
m=3/13
40
14m x 8m x 6m = 672 m^3
If 8m is its radius then the volume of the sphere is: 4/3*pi*8^3 = 2145 cubic m rounded
-8m = 48 m = 48/-8 m = -6
m2 + 8m - 65 = (m + 13) (m - 5)
d=n+8m
A rectangular prism 5 m by 8m by 9 m has a volume of 360m3
m2 - 8m + 16 = 0 (m - 4)2 = 0 so m = 4
It is 3 times 8 = 24 square m
If: 8m = 32m+96 Then: m = -4
