Its A or 6 because 30 divided by 5 is 6
Compose the quadratic condition in standard shape, ax2 + bx + c = 0. Recognize the values of a, b, c. Write the Quadratic Equation. At that point substitute within the values of a, b, c. Simplify. Check the arrangements.
The answer is D, you do everything two times
1.
x+4=3x
4=3x-x
4=2x
x=2
2.
x-8=-9
x=-9+8
x=-1
3.
4m+5-3m
4m-3m=-5
m=-5
