Check all of the expressions that are equal to the one below.
(9) • (-3+8)
a. (-3 + 8) • (9)
b. -(3-8) • (9)
c. (9.-3) + 8
d. (9) • (-3) + (9) • 8

(9) • (-3+8)

We know that (-3 + 8) • (9) is equal to the expression above because of commutative property.

If we apply the -1 on "-(3-8) • (9)" we get (-3+8)x(9) which looks exactly like the first answer choice.

Assuming that I'm reading the third answer correctly, it is not equivalent because the 9 has to be applied to the -3 and the 8 for distributive property to work.

The last answer choice is an example of distributive property and is equivalent.

answers: A,B,D

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

lol.

it's ok we all do this sometimes.
