Afabric store sells pieces of material for $5 each ali bought two white pieces and 8 blue pieces she also bought a pack of buttons for $3 the expression 5 x parentheses 2 + 8 parentheses + 3 gives the cost in dollars of a lease purchase how can you describe the term parentheses 2 + 8 parentheses in words

The expression in the parenthesis refers to the first pieces Ali bought for $5, the second term +3 refers to the cost of the pack of buttons.

Basically, 2+8 is grouped in a parenthesis because both have the same cost of $5, so in this case we can use the distributive property. So, that of the expression just represents that, the same cost for the first 2 whit pieces and 8 blue pieces.

The last term +3 is not included in the parenthesis because it refer to a pack of buttons that has a different costs, it would be an error to include it inside the parenthesis.

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
