Answer:
A)4
Step-by-step explanation:
degree measure of the 4 angles of a trapezoid is 360
so
since we have only 2 angles, 360/2
180=125+(14x-1)
180-125=125+(14x-1)-125
55=14x-1
55+1=14x-1+1
56=14x
4=x or x=4

Answer:
-70
Step-by-step explanation:
If a number is right by a parathesis () then you multiply the number inside the parathesis by the number next to them.
-x^2+2x+3=x^2-2x+3 add x^2 to both sides
2x+3=2x^2-2x+3 subtract 2x from both sides
3=2x^2-4x+3 subtract 3 from both sides
2x^2-4x=0 factor
2x(x-2)=0
So x=0 and 2
