The sum of the interior angles of an n-sided polygon is 5400 the value of n is?

32 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is (n-2)*180  where n is the number of sides

(n-2) * 180 = 5400

Divide by 180

(n-2) * 180/180 = 5400/180

n-2 = 30

Add 2 to each side

n-2+2 = 30+2

n =32

There are 32 sides

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
