Answer:
45 acres
Step-by-step explanation:65-20=45
3
Step-by-step explanation:
We know x = -2, so we can substitute -2 in for x
3x^2- 9
3*-2^2-9
Solve the exponent first (PEMDAS)
3*4-9
Multiply next
12-9
Subtract
28.26ft
A=πr^2
π*3^2=28.27433
28.26
Use PEMDAS:
[(30+6) -3^2] / 9* 2
= (36 -9)/ 9* 2
= 27/9* 2
= 3*2
= 6
The final answer is 6~
