Answer:
x = -0.62 and x = 4.29
These values are approximations !
Step-by-step explanation:
You can not use Factoring to solve this equation. Perhaps you did not use the exact notation as in the original question?
Anyway, to solve it, you can still use the ABC formula.
3x²-11x-6=0
a = 3
b =-11
c = -6
x = [11 + √{121 -4(3 *-6)} ]/ 2*3
x = [11 + √{121 -4(-24)} ]/ 6
x = [11 + √{121 + 96} ]/ 6
x = [11 + √{217} ]/ 6
x = 4.29 This is an approximation !
x = [11 - √{121 -4(3 *-6)} ]/ 2*3
x = [11 - √{121 -4(-24)} ]/ 6
x = [11 - √{121 + 96} ]/ 6
x = [11 - √{217} ]/ 6
x = -0.62 This is an approximation !

Wouldn’t be a,or d. I would honestly say B..
Answer:
X = -12.54 (I am a Math Class Topper in both 6th Grade an 7th Grade)
Step-by-step explanation:
5 x .27 = 1.35
8x - (3 x .27) = .81
1.35 + 8x - .81 = 7x - 12
- 7x - 7x
----------------------------------
1.35 + X - .81 = -12
+ .81 +.81
---------------------------
1.35 + X = -11.19
-1.35 -1.35
-----------------------
X = -12.54
Answer:
This construction shows how to draw the perpendicular bisector of a given line segment with compass and straightedge or ruler. This both bisects the segment (divides it into two equal parts, and is perpendicular to it. It finds the midpoint of the given line segment.
.75 is the same as 75 %, therefore the likelihood of you solving the brain teaser is 75% of the time. Hope that helped.
