18
Step-by-step explanation:
Write the expression
-2x²y
substitute the real values with x=-3 and y= -1
-2(-3²)×(-1)
-2(9)×(-1)
-18×-1

Arc PR is 156 degrees. Since both angles are are making the forming arc they should be congruent. You can put (5x+23)=(9x-21) which is x=11.
Then you plug in 11 into your equation; 5(11)+23=78.
Since the vertex is on the outside of the circle then the arc is forms is 2 times the value of the angle.
78(2)=156
5=54 because 3x4= 12 + 6x7=42
I am not 100% sure but I believe 6=11.8
9=37 because 7x3=21 + 2x8=16
