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 ar
ea of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y?

Answer:
5xy + 15x2 = 125
Step-by-step explanation:
5xy + 15x2 = 125
L = (x

Answer:
Step-by-step explanation:
The length of the rectangle is:
The width of the rectangle is:
The area of the rectangle, which is the product between length and width, is equal to 125 cm^2:
Substituting the expressions for L and W found before, we get:
