Answer:
12
Step-by-step explanation:
f(x) = -x^3 + x^2
Let x = -2
Evaluate the expression
f(-2) = -(-2)^3 + (-2)^2
= - (-2)*(-2) * (-2) + ( -2) * (-2)
= -(-8) + ( 4)
= 8 + 4
= 12
Answer:
a=1/2
Step-by-step explanation:
first we need to isolate a squared. so we add 1/4 to both sides
then you take the square root of a square to get 1/2
to check, 1/2 * 1/2 = 1/4
1/4-1/4 = 0
The two numbers are 12 and 16. 12 + 6 = 18. 6 doubled is 12. 12 plus 6 equals 18.
