Answer:
f(x) = 
Step-by-step explanation:
All you have to do is multiply (x + 1)(x + 2)(x - 4)
You should get 
So, f(x) = 
85 = 10x+15
70 = 10x
x = 7
180-85 = 95 = z
Answer:
base =5 because all angles=60, so an equilateral triangle
height=4.33
Step-by-step explanation:
height^2+1/2(5)^2=5^2
height^2+6.25=25
height^2=18.75
height=4.33
A=p(1-r)^n
A=24,000×(1−0.09)^(5)
A=14,976.77
