Answer:
The answer is B because it's all real numbers since it won't stop
Step-by-step explanation:
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
Perpendicular to x axis means then that the euation is x=something
given
(-5,-2)
(x,y)
so x=-5 is da equation
We know that
1 liter----------------> 1000 ml
J<span>ennifer punch is 5 liters----------------> 5*1000=5000 ml
</span><span>Her brother punch-------------------------> 750 ml
[total </span><span>two batches]=(5000+750)----------> 5750 ml
the answer part A) is 5750 ml
Part B) </span><span>how many 180 mL servings would they have?
</span>[180 mL servings]=5750/180=31.94-----------> 31
they would have 31 (180 ml servings)
punch left over=[5750-31*180]=170 ml
there would be 170 ml of punch left over
225.30816
Hope this helped :)))
