Question

Simplify each expression by distributing and combining like terms
8(x + 5) - 4(x + 4)

Answer 1

4x+24

Explanation:

To solve this problem, first you have to use the distributive property of
`\displaystyle a(b+c)=ab+ac`.

First, expand.

8(x+5)- 4(x+4)

8(x+5)

8*x=8x

8*5=40

8x+40

8x+40- 4(x+4)

-4(x+4)

-4*x=-4x

-4*4=16

-4x-16

8x+40-4x-16

Next, solve.

8x+40-4x-16=4x+24

Therefore, the correct answer is 4x+24.

Answer 2

4x+24

Explanation:

we have: 8(x + 5) - 4(x + 4)

we apply distributive property:

8*x+8*5-4*x-4*4

we have:

8x+40-4x-16

4x+24
