Question

The same style blanket in size B has width 2x + 10 and length 4x - 10. Write a polynomial

expression, in simplified form, that expresses the difference in area of the blankets A and B. Show

all your work.

Answer 1

Answer:A=8x^2 + 20x - 100

Explanation:

The area of rectangle is:

A= length × width

A= (2x+10)(4x-10)

So now expand the bracket8

A=8x^2 - 20x + 40x - 100

A=8x^2 + 20x - 100
