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
F(x) = 3x + 2
f(x + 3) = 3(x+3) + 2
f(x+3) = 3x + 9 + 2
f(x+3) = 3x + 11 (Answer)
HI umm.. I can see the thing that you need help with sorry not trying to be rude but what do you need help with?
Answer:
4x-2
Step-by-step explanation:
2x-5+5-x+3x-2
Add the values that are similar, so in this case it would be 2x-x+3x
and x by itself is one so I usually rewrite it to 1x and it might be easier to highlight the similar values like
2x-5+5-1x+3x-2
then you combine like terms to get
2x-x+3x and -5+5-2
x+3x -2
and then you'd get 4x-2
