8x-4=2x+35
8x-2x=35+4
6x=39
X=39/6
The nature of the roots can be determined by the determinant of the equation. The determinant is:
b² - 4ac
If this is positive, there are two roots
If this is 0, there is only one root
If this is negative, there are complex roots
Answer:
129
Step-by-step explanation:
the 2 angles together will equal 180 because that is half of a circle a circle is 360so what you do is subtract 180 minus 51 and get 129
im pretty sure you dont need exponents for this bud
3x-x-4x+4x
2x+0
2x
