Answer:
x= 8
Step-by-step explanation:
Half of a circle or a straight line is equal an angle of 180 degrees. Therefore, both the measurements of angles RPS and QPR are equal to 180 degrees.
3x + 12 + 7x + 88 = 180
Add like terms
10x + 100 = 180
-100. -100
10x = 80
/10. /10
x = 8
Simplify.
3x^2−7x+9 - 2x^2+4x−8
1. 3x^2-2x^2 = x
2. -7x + 4x = -3x
3. 9 - 8 = 1
Combine.
x -3x +1
Thus, 2x^2+4x−8 is x -3x +1 less than 3x^2−7x+9
