Answer:
1. x - 6
2. 3
3. 2x + 6
Step-by-step explanation:
1. Six less than a number means to "subtract 6 from a number". Hence, the algebraic expression is x - 6.
2. Product denotes multiplication. Hence, 3 times square of a number is 3

3. Sum denotes addition. Twice means two times. Hence, twice a number is 2x. The desired expression is 2x + 6 (you have to add 2x to 6 to get the sum)
