Answer:

Step-by-step explanation:
5x4+20x3-105x2
5x2( x^2 +4x -21)

9514 1404 393
Answer:
21
Step-by-step explanation:
When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.
KL·KM = KJ·KC
Assuming the marks inside the circle apply only to the lengths inside the circle:
8(8+x+5) = 7(7+2x+1)
104 +8x = 56 +14x
48 = 6x
8 = x
Then the measure of MK is ...
MK = x+13 = 8+13
MK = 21
There isn’t an exact answer without measurements, but she could measure how much lemonade there is without an ice cube, then add the ice cube and the difference is the volume
