12 divided by (6) + 4 squared as associative property

18

Step-by-step explanation:

Given 12 divided by (6) + 4 squared

Algebraic expression will be ⇒ 12 ÷ 6 + 4²

We will use associative property to solve the expression, we will combine some numbers and operations with parenthesis to do it first.

So, the given expression = 12 ÷ 6 + 4²

= 12 ÷ 6 + 4 × 4

= (12 ÷ 6) + (4 × 4)

= 2 + 16

= 18

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
