A healthy 140 pound boy needs between 2,000 to 2,400 calories a day.
Hope that helps :)
X+ 4? idk I don't really understand the question...
Step-by-step explanation:
Molly should have multiplied three first so that it would have been
x + 6 + 3x + 12
4x + 18
Dylan did not add x to 5x
it should have been
6x - 12
Jose did not multiply 7 and -5
it should have been
x + 3 + 7x - 35
8x - 32
