Answer:

Adam is 9 years old.

Step-by-step explanation:

Let d and c represent Adam's and Alicia's ages.

d = c - 15, and

c + 6 = 2(d + 6)

Rearrange d = c - 15 as c = d + 15, and then substitute d + 15 for c in the second equation. We obtain:

d + 15 + 6 = 2(d + 6), or

d + 21 = 2d + 12

Combining like terms, we get 21 = d + 12, or 9 = d.

If d = 9 then c = d + 15, or c = 9 + 15, or c = 24.

Adam is 9 years old.

Find the greatest common factor of these three expressions.

leva [86]

6x

42/6 = 7 (valid), 18/6 = 3 (valid), 12/6 = 2 (valid)

7, 8, 9, 10, and 11 are all not divisible by 12, and 12 is not divisible by 18, so 6 is the highest number.

Also, each number has at least one x, so you can take one out.

Remaining=
6x (7 + 3x^2 + 2x^3)
