Missing part of your problem there. If v=5, 3v=15. Assuming you're adding the 9, the answer is 24.
274.80 if you rounded to the nearest 10th but if you don’t it will be 274.78
The answer is 3,750. you would multiply 1250 by 3
True.
Distribute 3 to all terms within the parenthesis
3(4h + 2k) = 3(4h) + 3(2k) = 12h + 6k
hope this helps
