If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:
<span>x^2 + 9x - 22 = 0
</span>(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11
The correct result would be x = 2 and x = - 11.
Answer:
21: 35
Step-by-step explanation:
(I think you mean x2 is x squared correct? if so) x^2+x^2-5x-x+7
2x^2-6x+7
Step-by-step explanation:
125 is vertically opposite to the interior angle of triangle
then X+40+X+31+125=180(sum of angle of triangle is 180)
the we get X= -22
Add them all up and divide by 6
160/6 = 26.7
