If 3x + 4x - 4x = 36, then x

x=12

Step-by-step explanation:

3x+4x-4x=36

3x=36

x=12

12

Step-by-step explanation:

3x+4x-4x=36

the 4xs equal eachother out.

3x=36

3x/3=36/3

x=12

Hope this helps!

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
