Homer has made mistake in step 2
When you complete the square, you need to add the values to both sides of equation
<em><u>Solution:</u></em>
<em><u>Given equation of circle:</u></em>

Let us first calculate center and radius and find out where he did the mistake
<em><u>Step 1:</u></em>
Group the terms

<em><u>Step 2:</u></em>

But homers step 2 is:

So homer has made mistake in this step
When you complete the square, you need to add the values to both sides of equation
But homer did not add 49 and 1 to right side of equation
Correct steps are:

Comparing general equation of circle,

Therefore, center is ( 7, -1) and radius is 8.66
Answer:
50-45+87-25=67
Step-by-step explanation:
earning is + so +50
losing is - so -45
+87
-25
To do these problems, you plug in the ‘n’ value given into the equation.
a. 6j - 3 : j = 4
6(4) - 3
24 - 3
21
b. 1/2b + 5 : b = 14
1/2(14) + 5
7 + 5
12
c. 8 + 4k : k = 3.5
8 + 4(3.5)
8 + 14
22
Answer:
8={8,16,24,32,40}
6={6,12,18,24,33}
so the least common multiple is 24
