Alani is in charge of marketing for a travel company. She is designing a brochure that will have 6 photos. Suppose the dimensions of the narrower photos were increased to 2 in. by x in. What expression would represent the new arrangement based on the GCF?

Complete Question

Alani is in charge of marketing for a travel company. She is designing a brochure that will have 6 photos.

There are two main photos each of length x cm.

There are 4 long pictures each of 1 inch by x cm.

(a)Find the total area of the photos

(b)Find a rectangular arrangement of the photos and determine the factoring that represents this arrangement.

(c)Suppose the dimensions of the narrower photos were increased to 2 in. by x in. What expression would represent the new arrangement based on the GCF?

(a)

(b)2x(x+2)

(c)

Step-by-step explanation:

(a)Area of the Photos

Total Area =2(Area of Main Photos)+4(Area of Long Pictures)

(b)If we arrange the six photos in a rectangular array

We would have a photo of:

Height = x

Width =x+x+4 =2x+4

Therefore:

Area =x(2x+4)

We can factorize further to obtain:

Area =2x(x+2) sq. in.

(c)If the dimensions of the narrower photos were increased to 2 in. by x in.

Total Area =2(Area of Main Photos)+4(Area of Long Pictures)

The expression that would represent the new arrangement based on the GCF is: 2x(x+4)

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
