Answer:

a) 2(n + 5)

b) 2n + 5

Step-by-step explanation:

Writing an     algebraic expression:

  a) Sum of n and 5 ⇒   n + 5

     Twice sum of n and 5 ⇒   2*(n +5)  = 2*n + 2*5

                                                                = 2n + 10

b) Twice n ⇒ 2*n = n

Sum of twice n and 5 ⇒   2n + 5
