Answer:
Required output = 14
Step-by-step explanation:
Sum of the input 3 and 4 = 3 + 4
Twice the sum means two times.
So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.
2(3 + 4)
Perform the addition inside the parentheses.
2(3 + 4) = 2(7)
Now, multiply.
2(3 + 4) = 14
Hence, required output = 14
