I have answered this question before.
Given:
Bob has three kids whose ages has the product of 72. I will only be able to give you a set of 3 numbers to represent the ages. Had the sum of the ages been given, the specific ages would be provided.
I just did a prime factorization of 72.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72 ⇒ 2³ x 3²
There are a lot of possible combinations, here are a few.
1 x 8 x 9 = 72 ⇒ 1 + 8 + 9 = 18
1 x 4 x 18 = 72 ⇒ 1 + 4 + 18 = 23
<span>2 x 4 x 9 = 72 ⇒ 2 + 4 + 9 = 15</span>

Answer:
D
Step-by-step explanation:
they both equal each other. 5x+7=9x-63
then you would take 70 divided by 4
which equals 17.5
Answer:
