Question 108995: Can't get this one, any help would be great, thanks.
The length of a rectangle is 5 cm more than 4 times its width. If the area of the rectangle is 76 cm2, find the dimensions of the rectangle to the nearest thousandth.

Area of a rectangle :
L=5+4W
Substitute in the area equation.

((((5+4W)*W=76}}}

Use the quadratic formula,

Since a negative width doesn't make sense, we will only use the positive root.

Verify the area to check your answer.

Close enough, true statement.
Good answer.
