Answer:
I think this question is askingg fofr f(g(x)), in which case you are simply inserting g(x) into the f(x) solution, in this case 2 for x. This is because (f*g)(x)=f(g(x)).

Answer:
pic # 1 answer is B. 81 x pi
pic#3 answer is C. QC
Step-by-step explanation:
pic #1
the formula to find the area of a circle is pi x the radius to the second power
they give you the diameter. (18)
the radius is half of a diameter (d/2)
so 18/3 = 9
9 to the second power (9 x 9) = 81
so your answer is 81 x pi
pic#2
I don't much, but i do know they asking for the radius and since the radius is half the diameter of a circle then QC makes sense in my book.
hope this is helpful.
Answer:
-17.3
Step-by-step explanation:
37+x=15-2x
-x
37=15-3x
+15
52=-3x/-3
Well the formula for Volume of a Rectangular Prism is {Length x Width x Height = Volume}
So we know 18.5 x 9 x Length = 2,830.5
Divide by 18.5 and 9 and you are left with the length of 17 xD
