Question

Which algebraic expression models the given word phrase ? 2 times the sum of a and b

Answer 1

The answer is:

x=2a+b

Answer 2

`2(a+b)`.

Explanation:

We re asked to write an algebraic expression for the given word phrase.

The sum of 'a' and 'b' would be 'a' added to 'b' as:
`a+b`.

2 times the sum of 'a' and 'b' would be 2 multiplied to the sum of 'a' and 'b':
`2(a+b)`.

Therefore, our required expression would be
`2(a+b)`.
