Respuesta :

The simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.

What is an expression?

  • An expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.

To find the simplified expression:

Given -

  • Distance cycled = x² + 7 miles
  • Distance ran = 2x miles
  • Distance swam = x - 2 miles

Thus,

  • Total distance she covers = x² + 7 + 2x + x - 2
  • Total distance = x² + 3x + 5 miles

Therefore, the simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.
