Best Answer

length 14cm, width 2cm

This is worked out by finding the following equations:

perimeter = 16 x width

length = width + 12

Then working out

16 x width = 2 x (width + 12) + 2 x width

-> 14 x width = 2 x (width + 12)

-> 14 x width = 2 x width + 24

-> 12 x width = 24

-> width = 2cm

Since lendth = width + 12, length = 14cm

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
