Using the sum of interior angles formula;
(n-2)×180=sum
(n-2)×180=2880
n-2=2880/180
n-2=16
n=16+2
n=18
Therefore, this polygon would have 18 sides.
Hope I helped :)
<span>answer 1
Nancie is typing is represented by the equation
y = 35x
Therefore, the rate at which Nancie is typing is given by the slope of the straight line that in this case is:
35 words per minute
answer 2
To find the rate at which Suresh is typing we have to find the equation of the line with the data in the table.
For this case, the equation of the line will be given by:
y = 56x
Therefore, the rate at which Suresh is typing is given by the slope of the straight line which in this case is:
56 words per minute
answer 3
Nancie's rate = 35
Suresh's rate = 56
56-35 = 21 words per minute
Nancie's rate is 21words per minute less than Suresh's rate.

Step-by-step explanation:
w(2w - 30) = 5400
2w²- 30w = 5400
2w² - 30w - 5400 = 0
(w - 60 ) ( w + 45 ) = 0
w= 60 w= - 45
only take the positive value
therefore w = 60
G(h(0)) = 20
h(x) = x+4
h(0) = 0+4
h(0) = 4
g(x) = 5x
g(h(0)) = g(4) = 5(4) = 20
