Question

Last one was 5(x + y)

Answer 1

Answer:

1. 2x - 5

2. 5(x + y)

3. (5 - x)²

Step-by-step explanation:

1. Five less than the twice the number

Let the number be 'x'. 5 less than twice the number = 2x - 5

2. Five times the sum of two numbers

Let the two numbers be 'x' and 'y'. Then the notation would be: 5(x + y)

3. The difference of 5 and a number, squared

Let the number be 'x'. The mathematical expression for the above statement would be: (5 - x)².
