What is the midpoint of a segment whose endpoints are (9, −9) and (−3, 7)?

Find the greatest common factor of -30x 4 yz 3 and 75x 4 z 2.

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

Me. i can't figure out this question. give an explanation too. .
