1 and 2 i can't answer without proper data.
3. x+2x+2x+6 = 86
5x+6 = 86
-6 -6
5x = 80
x = 16
Side one: x is 16
Side two: 2x is 2(16) = 32
Side three: 2x+6 is 38
To do this, simply add the 2 functions-as it says:
(2x+1) + (-3x+4)
2x+1-3x-4
-x-3
Your answer is -x-3
answer and explanation are in the picture.
False...it does not include 3....it includes only numbers less then 3.
For it to include 3, u would need an equal sign in there..
Y < = 3...(thats less then or equal)...this would include 3
