Answer 1

(2a+1)(3+3)

(2a+1)(6)

6x2a + 6x1

12a+6

Answer 2

Answer:

12a + 6

Step-by-step explanation:

The question is half solved already.

We have to simply multiply the terms and then add them up.

3 ( 2a + 1 ) + 3 ( 2a + 1 )

= 6a + 3 + 6a + 3

Adding them up,

= 12a + 6

We can also solve as follows—

3 ( 2a + 1 ) + 3 ( 2a + 1 )

Taking out the common i.e. ( 2a + 1 ),

( 2a + 1 ) ( 3 + 3 )

= ( 2a + 1 ) * 6

= 12a + 6
