Which of the following expressions is equivalent to + ( 1/4y - 2 1/4y + 1/2 (4- 2y)?
Use the space on the right to show your work.
0 -3y + 2
0 -33 +2
0 -4y + 4
0 -4y+2

12.5 feet

step-by-step explanation:

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.

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.
