The new expression is 4.8d - 4.2c
<u>Explanation:</u>
<u />
Given:
Expression = (-7c + 8d) 0.6
On multiplication we get:
-4.2c + 4.8d
Therefore, the new expression is 4.8d - 4.2c
It's a computation. It would be 8!/3!(8-3)! If my memory serves me correctly.

You will have on real root, and two complex which derives from the 3rd degree polynomial function.
Angle TQS is equal to 74 degrees
Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
