Step-by-step explanation:
2x^2 + 17x -21 cannot be factored nicely, if it was +21 you could, but the zeros for this have to gotten using the quadratic equation
-b +/- (b^2-4ac)^1/2
2a
so
-17 +/- (17^2-4(2)(-21))^1/2
2(2)
-17 +/- (457)^1/2
4
so the zeros are roughly 1.094 and -9.594
Answer:
The value of x is equal to ![5](https://tex.z-dn.net/?f=5)
Step-by-step explanation:
we know that
The diameter divide the circle into two equal parts
In this problem
MO=NO
substitute the values
![5x-7=18](https://tex.z-dn.net/?f=5x-7%3D18)
solve for x
Adds 7 both sides
![5x=18+7](https://tex.z-dn.net/?f=5x%3D18%2B7)
![5x=25](https://tex.z-dn.net/?f=5x%3D25)
Divide by 5 both sides
![x=25/5=5](https://tex.z-dn.net/?f=x%3D25%2F5%3D5)
Answer:
The corresponding angle is 51 degrees, I'm not sure exactly what x is. I hope this helps a little bit.
