Let f (x) = (x3 + x) 2. Find the derivative of f (x).

Find the sum to the equation 3+6+9+

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

X2 + y 2 = 36 x + y = 6 solve the system of equations.
