Answer:
38724 is the answer but kinda confused on what u mean
Step-by-step explanation:
We have been given work of Riley. By looking at his work carefully, we have to identify the error. So let's start from beginning.

First line is just the question so there will be no error.
After that we try to factor denominators
STEP1: 
Factors are correct so no error in step1.
In step2, we have to find the common denominator which will be (x-2)(x-3)(x+3)
so that means she needs to multiply and divide 2nd term by (x-2)(x-3) while she multiplied by only (x-2). Which means she used wrong common denominator.
<u>Hence final answer will be "B. She used the wrong common denominator."</u>
The distance from city C to city D is 4,814 miles.
Answer:Instinctively one thinks geometrically: horizontal (X) axis and then vertical (Y) axis. This is not, however, the case with a 2D array, rows come first and then columns. Consider the following analogy: in geometry one walks to the ladder (X axis) and climbs it (Y axis).
Step-by-step explanation:
<h2><u>DIRECT RULE OF 3</u></h2>
We use a rule of 3 to solve it.
Let's record the data:
253 miles → 8 hours
x miles → 7 hours
Let's solve:



<h3><u>Answer</u>. The car can travel 221,375 miles in seven hours.</h3>
