If you plug that into a calculator you get 4.5

Find constant a.
----------------------------------------------------------------------------
Given that g(4) = 8
--------------------------------------
Substitute x = 4
--------------------------------------
g(4) = a(4)² + 24 = 8
16a + 24 = 8
--------------------------------------
Take away 24 from both sides
--------------------------------------
16a = 8 - 24
16a = -16
--------------------------------------
Divide by 16 on both sides
--------------------------------------
a = -1
Now that we know that a = -1, plug it back to the equation.
g(x) = -x² + 24
--------------------------------------
Find g(-4)
--------------------------------------
g(-4) = - (-4)² + 24
g(-4) = -16 + 24
g(-4) = 8
----------------------------------------------------------------------------
Answer: 8

Answer:
Can't factor..........
Step-by-step explanation:
If you are just simplifying it it would be 6x because it's 5x plus one more x but if you are trying to find x then I have no idea
