Answer:
Age= 15
Step-by-step explanation:
Let a be for age at the moment
(a-3)^2 =6(a+9)
a^2-6a+9=6a+54
a^2-12a-45
(a-15)(a+3)
a=15 or a=-3
Age cannot be negative (-)
Therefore
Age =15
X^3 + 7*x^2 + -16*x-112
=(x + 4)*(x + 7)*(x - 4)

Answer:
Step-by-step explanation:
(f + g)(x) simply means that you are adding together the 2 functions that are written in terms of x.

The only like terms we have there are the x-cubed's, so

Answer:
3x +3y +3h
that’s the farthest you can solve since you don’t know the variable’s values
