The answer is 10% because 10% of 40 is 4

above is the distance formula, plugging your numbers from P(x1,y1) and Q(x2,y2).

or
It would be 2.4 times 10. I got this answer because there is 24 shaded in, so I divided it by 10 and got 2.4. The other answers could also be 6 times 4, 8 times 3, 2 times 12, 1 times 24. I hope this helps. <3
Foil the right side. Multiply first, outer, inter, and the last terms. The right side is equal to x^2 + 11x + 18x. N is 11.
