Answer:

Step-by-step explanation:
Here we need to move the negative sign to the rest of the variables, and then only add the ones with the same power:

And then move the variables with the same power closer together

See how -x^4 and -2x^4 are together?
All we have to do now is combine.

So our answer is 
You are right! 6 2/3 is the answer
Step-by-step explanation:
10+3(x+2)=36
10+3x+6=36
16+3x=36
3x= 20
x=6 2/3

Answer:
z = 30; obtuse isosceles triangle
Step-by-step explanation:
4z + z + 30 = 180
5z + 30 = 180
5z (+ 30 - 30) = 180 - 30
5z = 150
5z/5 = 150/5
z = 30
Since z = 30, and 30 = 30, two angles are congruent to each other and there is only one obtuse angle. Therefore, this is an obtuse isosceles triangle.
