Suppose the Length and Width are L and W.

Then Perimeter: 2(L + W) = 44 so that L + W = 22 and W = 22 - L

and Area: L*W = 72 so that L*(22 - L) = 72

ie L2 - 22L + 72 = 0

(L - 4) (L - 18) = 0

Then L = 4 giving W = 18 or L = 18 giving W = 4

Since L > W (by convension), the answer is L =18 cm and W = 4 cm

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its area?

Let's take a look at this problem.Rectangle Perimeter = 2(l + w)Rectangle Perimeter =? 2(2l + 2w)Rectangle Perimeter =? (2)(2)(l + w)2(Rectangle Perimeter) = 2[2(l + w)]Thus, we can say that the perimeter of a rectangle is doubled when its dimensions are doubled.Rectangle Area = lwRectangle Area =? (2l)(2w)Rectangle Area =? 4lw4(Rectangle Area) = 4lwThus, we can say that the area of a rectangle is quadruplicated when its dimensions are doubled.
