Answer:
B
Step-by-step explanation:
The answer is 12 a this is how to solve it:
5a+3a+14+4(a-6)+10
5a+3a+14+4a-24+10
8a+14+4a-24+10
12a+14-24+10
12a-10+10
12a
1/2 x 44 is the correct answer. Since the answer to the main equation is 22.05, the closest answer to it is 1/2 x 44 which is 22.
V (cube)=9³=729 cm³
V (cone)=1/3*π*R²*H= 1/3*π*3²*9=84.8 cm³
V (metal)= 729-84.8=644.2 cm³
Answer: 21
Step-by-step explanation:
This means we can substitute x=5 into f(x), so f(5)=6+3(5)=21.
