. The net below shows the dimensions of Michelle’s living room. She is going to put wallpaper on the living room walls.

What is the difference, in square yards, between the total and lateral surface areas of the room?

4.2 x 6 = 25.2

4.2 x 3.5 = 14.7

4.2 x 3.5 = 14.7

Step-by-step explanation:

I multiplyed

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the answer is b.)

< 1=< 2
