Shelley's pet food store sold one customer 5 peanut butter biscuits for $3. She sold another customer 7 beef treats for $4.20. Write a proportion that compares the sales of these two items, and find the cross products. The cross products are both equal to .

The proportional equation is =

Cross product are both equal to 21.

Step-by-step explanation:

5 peanut butter biscuits for $3

7 beef treats for $4.20

So, proportional equation is

=

Cross multiply

21=21

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
