Answer:
16
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here the sum is 2520, thus
180° (n - 2) = 2520 ( divide both sides by 180 )
n - 2 = 14 ( add 2 to both sides )
n = 16
The polygon has 16 sides.
Answer:
ANSWER IS A I THINK
Step-by-step explanation:
Answer:
9t^2+(t+2)^2
Step-by-Step:
t is 9 X t, or the product of 9 and t. ^2 is squared while + is increased t+2 is the sum of t and t. the ^2 after the parenthesis is indicating the "square of t and 2"
Let x be the percentage required
25x=12
x=0.48
x=48%
Thus the ans is 48%

F(-9)
f(x)=-5x-2
=-5(-9)-2
=45(-2)
=90
g(-2)
g(x)=3xsquared-21x
=3(-2squared)-21(-2)
=3(4)+42
=12+42
=54
