Formula Used :  A( B + C )  =  AB + AC

a)

3(x + 1) + 3  =  3(x) + 3(1) + 3

                       =  3x + 3 + 3

                    =  3x +  6  

b)

5(1 + n) + 6  =  5(1) + 5(n) + 6

                        =  5 + 5n + 6

                        =  5n + 11

c)

5(a + 2) + 2(a + 3)  =  5(a) + 5(2) + 2(a) + 2(3)

                               =  5a + 10 + 2a + 6

                               =  7a + 16

Answer :

a) 3(x + 1) + 3  =   3x + 6

b) 5(1 + n) + 6  =  5n + 11

c) 5(a + 2) + 2(a + 3)  = 7a + 16
