Answer:
-12
Step-by-step explanation:
f(-3)= -(-3)2 + 6(-3)
= -(-6) -18
= 6 - 18
= - 12
Answer:
Neither even nor odd.
Step-by-step explanation:
f(x) = 2(x + 1)^3 = 2x^3 + 18x^2 + 54x + 54
f(-x) = -2x^3 + 18x^2 - 54x + 54
If it was even f(x) would be = f(-x) so it is NOT EVEN.
-f(x) = 2x^3 - 18x^2 + 54x - 54
So f(-x) is not = -f(x) so it is not ODD either.

Step-by-step explanation:
Answer:
13 and 16.
Step-by-step explanation:
Let the 2 parts be x and y, then:
x + y = 29
x^2 + y^2 = 425
From the first equation y = 29 - x so substituting in second equation, we get:
x^2 + (29 - x)^2 = 425
x^2 + 841 - 58x + x^2 - 425 = 0
2x^2 - 58x + 416
x^2 - 29x + 208 = 0
208 = 2*2*2*2*13
= 16 * 13
So factoring we get:
(x - 13)(x - 16) = 0
x = 13 ,16
So the numbers are 13 and 16.
