Answer:5
Step-by-step explanation:
The answer would be 28.26.
The reason this would be the answer is because radius is half of a circle and diameter goes through the entire circle the formula for this problem would be
Circumference= 

and the tent has radius of 3m which means we have to multiple 3 × 3 to get 9m and then we would multiply 9 × 3.14 = 28.26
Is it 2 times x squared (2x^2?
2 * 6^2
2 * 36
72
Answer:
a) x=3
b) x=4.5
Step-by-step explanation:
2(5x – 3) = 24
10x-6=24
10x=30
x=3
5(2x + 1) = 50
10x+5=50
10x=45
x=4.5
F(x)=x^2
x=-1→f(-1)=(-1)^2→f(-1)=1
g(x)=1/(2x+3)
g(f(-1))=g(1)→x=1→g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5
Answer: Option C.) 1/5
