Question

Express the area of the entire rectangle. Your answer should be a polynomial in standard fo

Answer 1

• x² + 9x + 8

====================

Sides of rectangle are:

• w = x + 1 and l = x + 8

Area equation:

• A = lw

The area is:

• A = (x + 1)(x + 8) = x*x + x*1 + x*8 + 1*8 = x² + 9x + 8
