Answer:
-3 plus/minus square root 17 over 4
Step-by-step explanation:
2x squared = -3x + 1 is the same as 2x squared + 3x -1
a=2 b=3 c=-1
sub those into the formula and you get -3 plus/minus square root of 9 + 8 over 2×2
and then you simplify
Answer:
D. 12
Step-by-step explanation:
Based on the Angle Bisector theorem, the opposite sides of ∆ABC are divided into proportional segments alongside the two other sides of the triangle, as BD bisects the <ABC. This implies that:
AB/AD = CB/CD
Substitute
AB/8 = 6/4
Cross multiply
AB*4 = 6*8
AB*4 = 48
AB = 48/4
AB = 12
