Answer:
B. 6 sides
Step-by-step explanation:
Interior angles of a n side Regular Polygon = (180n – 360) / n
120 = (180n – 360) / n
120n =180n - 360
180n - 120n = 360
60n = 360
n = 6
check: sum of interior angles of 6 side polygon: 180 * (6-2) = 720
720/6 = 120
Answer:
C. 70
Step-by-step explanation:
Answer:
the answer is D
Step-by-step explanation:
if you look on the graph and compare the statements you'll see none of them correlate except for the last one. 7 erasers cost 3.50, since the point on the graph is (7, 3.50)
(3x^2 + 25x + 8)
(3x + 1 )(x + 8)
hope this helps :)
I think the answer is x=0 the equation is not set up clearly
