Answer:
It A
Step-by-step explanation:
6 times -2 is -12
6 + -2 is 4
And x +x is x^2
2 years
Tina planted a tree. It started at 6 feet and every year it grows another three feet. The expression representing this is 6 + 3x, where x represents years.
Tinas neighbor also planted a tree where each year (which we called x) it grows 6 feet. The expression to represent this is 6x.
If you want to know when they’ll be the same height, then you need to set the expressions equal to each other.
6 + 3x = 6x
To solve, first get the variable to one side
6 = 3x
Divide each side by 3
x = 2
The trees wi be the same height the 2nd year.

Answer:
2x - 2 = 14
Step-by-step explanation:
Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2
So then
x + x - 2 = 14
2x - 2 = 14
You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:
2x = 14 + 2
2x = 16
x = 8
So Fran has 8 hats and Elena has 6 hats.

Answer:
x=4
Step-by-step explanation:
EF is half of the top and bottom lines comined so you would make an equation:
5x+8/2=2x+6
5x+8=4x+12
x=4
