The expression 2 + 3(x + 3) + x is simplified correctly in the correct order. which of these steps has an incorrect justification?

c. is incorrect

Step-by-step explanation:

2 + 3(x + 3) + x

use the Distributive property a(b + c) = ab + ac

= 2 + 3x + 9 + x     a. is correct

use the Commutative property of addition: a + b = b + a

= 2 + 9 + 3x + x     addition

= (2 + 9) + 3x + x

= 11 + 3x + x        b. is correct

use the Distributive property a(b + c) = ab + ac

not Associative property (a + b) + c = a + (b + c)

= 11 + (3 + 1)x      c. is incorrect

= 11 + 4x

use the Commutative property of addition: a + b = b + a

= 4x + 11

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
