2(b+3c) equivalent expressions Options: 3(b+2c) (b+3c) +(b+3c) None of the above

Lana71 [14]

2(b + 3c) → We first need to simplify this.

Simplify.

2b + 6c

1st Option :

3(b + 2c)

Simplify.

3b + 6c

This is INCORRECT, as it is not equal to 2b + 6c.

2nd Option :

(b + 3c) + (b + 3c)

Simplify.

2b + 6c

This is CORRECT because 2b+6c = 2b+6c

(b + 3c) + (b + 3c) → Answer
