Question

RECTANGLES The perimeter of Rectangle 1 in feet is given by P=36x–4 . The perimeter of Rectangle 2 in feet is given by P=26x–12 . Write a polynomial equation D for the difference in the perimeters of Rectangle 1 and Rectangle 2 given the perimeter of Rectangle 1 is greater. D= x Predict the difference in perimeters when x=9 . feet

Answer 1

36×-4=-144÷2=-72

26×-12=-312

the difference is the for the first question i did ########## i got -72 abd 2 questing i did ########## i got -312
