Answer:
C
Step-by-step explanation:
I know 17. The formula for INTERIOR angles is 180(n-2) divided by n. therefore 180(6-2) / 6 = 180 x 4 / 6 = 720 / 6 = 120.
and EXTERIOR angles is 360 divided by n, therefore 360/6 = 60.
Answer:
y = x² − 6x − 27
Step-by-step explanation:
To distribute, you can use something called FOIL. It stands for First, Outer, Inner, Last.
First, multiply the First term in each factor.
x · x = x²
Now multiply the Outer terms in each factor.
x · 3 = 3x
Next multiply the Inner terms in each factor.
-9 · x = -9x
Finally, multiply the Last terms in each factor.
-9 · 3 = -27
Add them all up:
x² + 3x − 9x − 27
x² − 6x − 27
Answer:
C(x)=25x+6000
b=2250
Step-by-step explanation:
C(x)=mx+b
m-marginal cost
x-no items
finding B
C(x)mx+b
6000=25(130)+b
b=2250
General substitution
C(x)=25x+6000
