Simplify: 3(3a + 4b)

can u please give me the answer and tell me how u got it :)

Answer 21ab

Step-by-step explanation:

First you do 3 times 3a which you get 9a then to 3 times 4b and you get 12b. So 12b plus 9a equals 21ab

9a+12b

Step-by-step explanation:

use the distributive property

since the three is on the outside of the parethesis distribute it

3x3a= 9a

then do the same with 4b

3x4b= 12b

final answer

9a+12b
