Please help Im giving 25 points

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

Hi, can anyone show me how to do this problem? 100 points for this. in advance

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?
