Which expression represents the greatest common factor (GCF) of 120 and 168? A. 2 x 2 x 2 x 7 B. 2 x 2 x 2 x 5 C. 2 x 2 x 2 x 3 D. 2 x 2 x 2 x 3 x 5

C.  2 x 2 x 2 x 3

Step-by-step explanation:

2 x 2 x 2 x 3 = 24, which is the greatest common factor of 120 and 168.

darn right!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
