1. The answer is letter b. four more than twice a number.

Given number = 2n + 4,

=> 2n = twice a number, n represents the unknown number

=> + = add or more than

=> 4 = four

So, this can be say as = twice a number more than 4, or four more than twice a number.

Thus, the given equation’s answer is letter B. four more than twice a number

=> Four = 4

=> more than = +

=> twice a number = 2n

=> 4 + 2n, the same as 2n + 4
