Choose all the expression with accurately written descriptions

All except 4th and last.

Step-by-step explanation:

The one that says equation is definitely wrong because it doesn't have an equal sign anywhere (there is nothing to solve there).

The one that says 5 plus x^2 that means 5+x^2 instead of 5x^2.

They should have said 5 times x^2 there which actually means 5x^2.

So I don't like the way some of these are written but the only two that are really wrong are the 4th one and the last one.

black lol

h

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

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.
