Simpler form of
(-4m ^ 3 - m + 9 ) - (4m ^ 2 + m - 12)

Factor this polynomial completely x^2-64

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
