What math are you in because I can ask my friends for help
Answer:
4y
Step-by-step explanation:
y + y + y + y = 4y
It's the first one.
If you work backwords, I'd say it's easier. 3y swuared is 9y2, and 11 squared is 121. Then just keep the sign the same
So volume of a cube=edge legnth cubed so take the cube root of 1000 and get 10
the side legnth is 10 feet
A constant because it a number
