Answer:
4/5
Step-by-step explanation:
Common factor is 3 so,
if you divide 12/15 by 3, then it will equal to 4/5
Answer:
3x² – 2x – 8
=> 3x² – 6x + 4x – 8
=> 3x( x – 2 ) + 4( x – 2 )
=> ( 3x + 4 ) ( x – 2 )
Therefore,
Either, 3x + 4 = 0
3x = - 4
x = - 4/3 (Ans)
And,
x – 2 = 0
x = 2 (Ans)
Answer:
m (slope) = 
Step-by-step explanation:
point-slope form: m= 
(4, 5) (2, -6)
x1 y1 x2 y2
-------------------
= m
-6 - 5 = -11
2 - 4 = -2
m =
-3, 3, 5.

Answer:
A = 37 degrees ; B = 82 degrees
Step-by-step explanation:
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees
