The answer is D. 15pi ft cubed
Answer:
true for sure it \s pretty easy to do but hard to explain
Let's find out.
David needs to score an average of 145 across all four games, so first we do:
145 × 4 = 580
Then we add all the scores he currently has:
139 + 143 + 144 = 426
Then we subtract 426 from 580 to find out how much he needs to score for his fourth:
580 - 426 = 154
David needs to score 154 on his 4th game to have an average score of 145 for all 4 games.
Once again if the numbers after x are supposed to be exponents(the raising power) then the answer will be -5
