Hey, it&#x27;s clear. So when you&#x27;re in here so we have X square is equal to why minus four kids, we have two points. He, uh, when comma five, two, meet comma, Ain&#x27;t birth gonna solve for X? We get plus or minus square e of why minus four. Cute. We know that the points of positive X coordinates. So we&#x27;re only then I used the positive, so e equals a lie minus four to the 3/2 policy. We&#x27;re gonna find d X over D Y in the equals three house. Why? Minus four? No one. How Now we&#x27;re gonna plug it into our equation. Park links equations from five to eight. Square root of one plus nine over four times. Why minus four day? Why? It&#x27;s five and eight since we&#x27;re finding it in respect to why we&#x27;re integrating in respect to why who has becomes equal to from 5 to 8. Square of one plus nine over four. Why minus and nine. Do you? Why becomes a full too integral five square root of nine. Why minus 32 Do you know why I put a 1/2 here? Louis, integrate this. It becomes on the house times, 2/3 times won over nine times nine. Why minus 32 to the three halves, 5 to 8. This is around one over 27. I&#x27;m 80 square of 10 minus 13 square of 13 which is around seven point 6337
