All terms have an x in them, so you factor that out first to get
Now the 2nd degree equation will be of the form (3x- ... y)(x- ... y) and by just trying you find that the ... is just 1. So the factorization is:
Your answer would be c please mark brainly I need one more for next rank
Answer:
b = -6.5
Step-by-step explanation:
92 - 16b = 12
now you want to get the number(s) and variables on different sides
92 - 16b - 92 = -16b
12 + 92 = 104
-16b = 104
now divide each side by -16
-16b / -16 = b
104 / -16 = -6.5
b = -6.5
Answer:
m<4 = 44°
Step-by-step explanation:
m<8 = 34°
m<9 = 40°
m<3 = 62°
m<2 = 34° + 40° (exterior angle theorem of a triangle)
m<2 = 74°
m<3 + m<4 + m<2 = 180° (sum of ∆)
62° + m<4 + 74° = 180° (substitution)
m<4 + 136° = 180°
m<4 = 180 - 136 (substitution property of equality)
m<4 = 44°
just divide 20 by coefficient of x
x < 20/2
x < 10
