5(2x+3)

=10x+15  Multiplied the bracket by 5

A. 10x+3 no

B. 10x+15 yes

C. 8x+2x+15 yes

D. 25x no

Answers are B. (10x+15), C.(8x+2x+15)

5(2x + 3)

Distribute the 5 to the number in the parentheses. In other words multiply 5 to  every number inside the parentheses, these being 2x and 3. So...

(5)(2x) + (5)(3)

10x + 15

So one of the answers will be B.

10x can be split up. 8x plus 2x is equal to 10x therefor another of the answers is C. 8x + 2x + 15

Hope this helped!
