Answer:
He answered 20 questions correctly.
Step-by-step explanation:
25×.8(80%) = 20.
Perimeter = 2(l+w) or 2(length+width)
So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38
Subtract 62-38 to get 24.
You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.
D. x - 9y + 4 = x + 4 + (-9y)
