Set the equation equal to 0
The zeros are {0,-2,-3}
So since the formula for the sum of a polygon's interior angles is (n-2)180, just make that equal to 2520 and solve for n, which is the number of sides.
STEPS:
1) (n-2)180 = 2520
2) n-2 = 2520/180
3) n-2 = 14
4) n = 16
So the polygon must have 16 sides
merle would have 85 and alex would have 77 by january so Merle will have more
Answer:
90.8
Step-by-step explanation:
w = 80 + 5.4t (fill in your variable t, the number of months)
w = 80 + 5.4(2) (Combine parentheses first)
w = 80 + 10.8 (Add the two together)
w = 90.8 (Your answer)
I hope this helped :)
