Select all expressions that are equivalent to (2n+6)(n+3)

(2n+6)(n+3)=

(2*n+2*3)(n+3)=

2(n+3)(n+3)=(1)

2(n+3)^2=(2)

2(n^2+2*n*3+3^2) =

2(n^2+6n+9)=(3)

2n^2+2*6n+2*9=

2n^2+12n+18 (4)

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
