Answer:
x = 8 or x = -1 is the answer
Step-by-step explanation:
3x² - 21x -24
divide with 3
x² - 7x - 8
Factorizing,
x² + x - 8x - 8
x(x + 1) -8 (x + 1)
(x - 8) (x + 1)
x = 8,-1
A. 18m+45=t
m=months
t=total cost
b.
1 month=$63
6 months = $153
12 months (1 year)= $261
22/7 is pie just in fraction form which makes it very logical depending on the problem.
If x = -4
f(x) = (-4)^2 = 16
if x = 4
f(x) = √4 = 2
hope it helps
