<p>Can someone please throughly explain this problem. I just can't seem to understand it.</p>

<h1>20 from the Math section.</h1>

2

<p>Type the question out and draw a picture of any diagrams and I can help you.</p>

3

<p>Points A, B, and X do not all lie of the same line. Point X is 5 units from A and 3 units from B. How many other points in the same plane as A, B, and X are also 5 units from A and 3 units from B. </p>

<p>A. None
B. One
C. Two
D. Four
E. More than four</p>

<p>I thought the answer was two, but it ended up being one. I really don’t understand why B. One is the answer.</p>

4

<p>Well there are TWO points that exist but the question asks how many OTHER points exist. There is only one OTHER point that exists.</p>

5

<p>Okay, so for this, you are going to want to draw a triangle.</p>

<p>If you flip the triangle over a horizontal line, you get X being 3 units from B and still 5 units from A. Also, you could plot X on the line and have it be 3 units from B and 3 from A, but the first sentence of the question clearly says “DO NOT ALL LIE ON THE SAME LINE.”</p>
