The area of a rectangle can be expressed by 2x^2 -7x - 4. If the rectangle has an
area of 45, find the positive value for x.

The area of a rectangle is 54x^9y^8 square yards.if the length of the rectangle is 6x^3y^4 yards,which expression represents the width of the rectangle in yards

How many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

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
