Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

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
