Simplify in this context means factorize, which we can do by extracting the common factor 4, which is present in every term of the expression. So, it would result
Remember that to extract a common factor, we just have to divide that factor from each term, and then place it in front of the expression as a factor.
How much bigger is B than A , so Side length B- A = (-4x+18) - (2x-7) = -6x+25 So perimeter = 4x length = 4x(-6x+25) = -24x+100 = 100-24x How much bigger? 100-24X
