Answer:
64
Step-by-step explanation:
You open up the (3x+5)^2 and get:
9x^2 + 30x + 25
So...
a+b+c = 64
OR
You add the coefficient(s) and the constant together in the parentheses and get:
(3x+5)^2 --> (8)^2
So you square the 8 and get:
The arc length of the semicircle is half the circumference of the full circle
90
60
5
-10
-25
-45
Do the biggest number. Then count down. When you get to negative number the smallest negative is the biggest number because it is closer to zero.
