Answer:
- 18x + 15
- 3(6x + 5)
Step-by-step explanation:
Unfortunately you didn’t provide the expressions to chose from ,however we can get other expressions From this one like this:
5(4x+3) - 2x = 20x + 15 - 2x
= (20x - 2x) + 15
= 18x + 15
we can also write 18x + 15 = 3×(6x) + 3×(5x) = 3(6x + 5)
then
these two expressions :
are equivalent to 5(4x+3) - 2x

Answer:
6 games.
Step-by-step explanation:
Given that,
Monthly membership fee of store 1 is $7.5, but then the charge to rent a game is only $1.00
Another store has no membership fee, but that store charges $2.00 to rent a game.
Let there be n games needed to be rented each month for the total fees to be the same from either store.
Cost of first store = $7.50+$1.00n
Cost of another store = $2.00
If cost equals,
$7.50+$1.00n=$2
n=5.5
6
Hence, 6 games needed to be rented each month.
