24 feet, 40 feet, and 56 feet this is because using the ratio given 3:5:7
you can multiply
3x8=24
5x8=40
7x8=56
This shows that it follows the ratio lastly you need to make sure the numbers add up to 120
24+40+56=120
So A is your answer can I be marked brainiest please
If x = 16 and y = -16, then x+y = 16+(-16) = 0
Alternatively, if x = -16 and y = 16, then x+y = -16+16 = 0
So y = -x and x can be equal to either 16 or -16
The answer is 4x+2 , hope this helps
