I find it easier just to graph this sort of question rather than multiply it all out.
x = 3.5
_____
(x^2 +2x +1) -(x^2 -6x +9) = 20
.. 8x -8 = 20
.. x = 28/8 = 3.5
Answer:
3a + 7b + -17
You have to combine the like terms

Answer:
Step-by-step explanation:
Let the exterior angle = x
Interior angle = 5x
x + 5x = 180 { interior angle and exterior angle are linear pair}
6x = 180
x = 180/6
x = 30
Interior angle = 5*30 = 150
