Answer:
2/6 = 48/144
7/8 = 168/192
Step-by-step explanation:
Use the least common denominator to write an equivalent fraction for each fraction. 2/6 , 7/8 The least common denominator is 24 .
2/6 can be rewritten as __
We Multiply both numerator and Denominator by 24
48/144
7/8 can be rewritten as __
We Multiply both numerator and Denominator by 24
168/192
For this case we have the following functions:

We must subtract the functions:

We build a table of values for 

Answer:

Let the integers be x-2, x, x+2.
Given,
x -2 + x + x + 2 = 69
3x = 69
x = 23
Hence, the integers are 21, 23 and 25.
In both cases,

(as a consequence of the interesecting secant-tangent theorem)
So we have
10.





(omit the negative solution because that would make at least one of AB or AD have negative length)
11.




(again, omit the solutions that would give a negative length for either AB or AD)
$122.57 • 4 + $555.28 = $1,045.56
$136.71 • 4 + $585.34 = $1,132.18
$1,132.18 - $1,045.56 = $86.62
