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:
B. 31°; 106° and 43°.
Step-by-step explanation:
1) the rule is:
(5x-7)+(3x+1)+(11x-4)=180°;
2) if to solve this equation, then x=10°;
3) if x=10, then after the substitution the answer is 43;31;106.
Try 6578 :) I think that may be right,

Answer:
<u>5 127/200 meters</u>
Step-by-step explanation:
4 1/2 = 4 5/10 | 4/5 = 8/10
--------------------------------------
4 5/10 = 4.5 | 8/10 = 0.8
--------------------------------------
4.8 divided by 0.8 = 5.625
--------------------------------------
5.635 = 5 635/1000
635/1000 divided by 5 = 127/200
--------------------------------------
5 + 127/200 = <u>5 127/200</u>
