The simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.
<h3>
What is an expression?</h3>
- 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.

The complete question is given below:
Joy is training for a triathlon. She runs a distance of 2x miles, cycles a distance of (x2 + 7) miles, and swims a distance of (x - 2) miles. Which simplified expression is equivalent to the total distance, in miles, Joy covers?
(A) x2 + 3x + 5
(B) x2 + 3x + 9
(C) 3x2 + 5
(D) 3x2 + 9
5x = five times x.
Not to be confused with X^5 (sometimes accidentally written as x5) which means x to the fifth power.

Answer:
(0, 2) and (- 1, 4)
Step-by-step explanation:
The solutions to the system of equations are at the points of intersection of f(x) and g(x)
These are at (0, 2) and (- 1, 4)
Ten times 5280 is clearly more than fifty thousand. Since there are more than ten inches in one foot, we have even more than ten times 5289 inches in a mile, so there are many more than 50000 inches in one mile.
