I need help please: Common Monomial Factors

A. Only Ivan
B. Only Javier
C. Both Ivan and Javier
D. Neither Ivan nor Javier

Only Ivan

Step-by-step explanation:

First of all - never do what Javier did!! You can’t separate things like that. It’s a violation of math (also it breaks my heart, and you don’t want that!).

Ivan is correct in taking out a factor of 2 from both the top and bottom.

6x+4 = 2(3x+2)

12x+4 = 2(6x+2)

The twos cancel, and you get 3x+2 / 6x+2.

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.

hi how are you doing today? if you ever need just tell me
