Help? Three students were given the expression shown to simplify. Use the drop-down menus to complete the statements about whether each student's answer is an equivalent expression. Then choose an expression that is equivalent. The first box’s options are: Correct / Incorrect The rest are in the other images

Tessa: -21x - 26

Bernette: -15x + 20

Lucy: 30 - 21x

Step-by-step explanation:

Put all like terms together

Tessa: 2 - 21x - 28

a) 2- 28 = - 26

Bernette: -5(3x-4)

1) You must multiply (-5) by 3x - 4

* -5(3x) = -15x

* -5(-4) = 20 (remember a negative X a negative = positive

Lucy: 2 - 21x + 28

Put all like terms together

a) 2 + 28 = 30

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
