18a: 3*3*3*2*a
20a: 2*2*5*a
6a: 3*2*a
the greatest common factor is 2a
180 is the degrees a straight line segment is. This means that
4x + 3x + 2x = 180.
Since these all have the same variable (x), then you can add the coefficients. (4,3,2)
9x = 180
180/9 = x
X = 20
Answer:
20
Step-by-step explanation:
20+20=40
Slope = -1/4
(4, 7)
y - 7 = -1/4 (x - 4)
y - 7 = -1/4x + 1
y = -1/4 + 8
answer is C
