Answer:
8)61.5 9)42.1
Step-by-step explanation:
8)61.5
area of square 10×10=100
circle=pie r^2
3.5^2×pie
=38.5
100-38.5=61.5
9)14×14=196
14/2=7
7=radius
pie×7^2
=153.9/2(because circle is half)
=76.95
76.95×2
=153.9
=196-153.9
42.1

Add up the lengths of the several sides of the polygon.
Examples: The perimeter of a triangle is the sum of the lengths of the 3 sides.
The perimeter of a hexagon is the sum of the lengths of the 6 sides.
And so on.
I highly recommend drawing any polygon whose perimeter you wish to calculate.
Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56
0, 1/3, 2/3, 1, 1 1/3, 1 2/3, 2
26 would be the correct answer because 2/3 X 40 = 26.667 but you cant serve a little bit of soup so the total would be 26 Hoped this helped
