Answer:

1. x+4x

2. 5x

3. [tex]6\frac{7}{x}[/tex]

4. 4x-2x+15

5. [tex](6+x)^2[/tex]

Step-by-step explanation:

To write expressions remember these key words:

  • a number is a variable like x
  • sum is +
  • difference and subtracted is -
  • quotient is ÷
  • product is ×
  • reciprocal means flip like [tex]\frac{1}{9}---> \frac{9}{1}[/tex]
  • square is an exponent of 2 like [tex]x^2[/tex]

1. x+4x

2. 5x

3. [tex]6\frac{7}{x}[/tex]

Remember a quotient would be [tex]\frac{x}{7}[/tex]but the reciprocal is [tex]\frac{7}{x}[/tex].

4. 4x-2x+15

5. [tex](6+x)^2[/tex]
