I got the answer 2x^(5/2) y^5 but it was wrong. The right answer is( 2y^5 radical x)/x^3

I need help figuring out how to find the sides lengths

25m^5n - 10m^4n + 15m^3n / 5m^3n Is the correct answer 5m2 - 2m + 3

I was given the answer which is (x-3) / (x-2) I just don't understand how to get there. I have gotten as far as factoring the numerator to (x+6)(x-5) and the denominator to (x+2)(x-2).&nb...

x8-x4+x2-x+2688 divide by x+7

(6t3+5t2+9)÷(2t+3)

36m5n5 ÷ (12m3)

please show the work

x8-x4+x2-x+2688 divide by x+7

explain how you can determine the height of a three-dimensional rectangular object given its area and volume.
