Answer:
12
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 3, 6 ] , then
f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56
f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then
average rate of change = 
= 
= 12
Answer:
b =✓45
Step-by-step explanation:
9^2-6^2
√45
b= ✓45
a. (-1,-1) you can solve the vertices of / and RX is a median
<span>C. 2* (3 + 5)^2 = 128 is the correct answer.

perimeter=2(85)+π(12.5)=220+2×12.5π
=170+25×3.14
=170+78.5
=248.5
distance ran=3×248.5=745.5 yards.
i hope this work for you
