Answer:

-3x^4+3x^3+8x^2-2x-5

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:

(-2x^4-2x^3+8x^2+2)-(x^4-5x^3+2x+7)\\-2x^4-2x^3+8x^2+2 - x^4+5x^3-2x-7

And then move the variables with the same power closer together

-2x^4-x^4-2x^3+5x^3+8x^2-2x+2-7

See how -x^4 and -2x^4 are together?

All we have to do now is combine.

-2x^4-x^4-2x^3+5x^3+8x^2-2x+2-7\\-3x^4+3x^3+8x^2-2x-5

So our answer is -3x^4+3x^3+8x^2-2x-5

Someone help me please!!!!<br><br>hurry

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.
