11/7 just flip the numerator and the denominator
Answer:
-46, 8, 28
Step-by-step explanation:
Supplementary means the 2 angles add up to 180 so...
124+(2x+4)=180
124+2x+4=180
124+2x+4-4=180-4
124+2x=176
124-124+2x=176-124
2x=52
2x/2=52/2
x=26
plug in and check
124+2x+4=180
124+2 (26)+4=180
124+52+4=180
176+4=180
180=180
Answer:
Step-by-step explanation:
Rearrange the given x^2+3=9x in standard quadratic form:
1x^2 - 9x +3 = 0
Then the three coefficients are a = 1, b = -9 and c = 3.
The discriminant is √(b^2 - 4ac), or √(81 - [1][3]), or √78.
± √78
Thus, the roots are x = ----------------
