Question

For each expression write an equivalent expression without parentheses: 4(3x+5) 4(3x-5) -4(3x+5) -4(3x-5)

Answer 1

You have to distribute to make an equivalent expression by using the distributive property

Answer 2

What happens if you just give me the answer? Do you get kicked off of open study or something? Lol just wondering.

Answer 3

-4(3x-5)
-4 x 3x= -12x
-4 x -5= 20
-12x + 20 is your finally answer

now use the distributive property with the rest of the problems

Answer 4

Thanks!

Answer 5

Are those all four answer to the four questions?

Answer 6

I am going to write a rules you shall apply.

1) \(\large\color{slate}{ \color{red}{a}(\color{blue}{b}+\color{green}{c})= \color{red}{a} \cdot \color{blue}{b} ~+~\color{red}{a} \cdot \color{green}{c} }\)

2) \(\large\color{slate}{ \color{red}{a}(\color{blue}{b}-\color{green}{c})= \color{red}{a} \cdot \color{blue}{b} ~-~\color{red}{a} \cdot \color{green}{c} }\)

Answer 7

In this case, yes.

Answer 8

in any case. (if you are referring to my rules)

Answer 9

these rules are very helpful if you have to distribute anything
