the subset of -3 and 8 is: { }, {-3}, {8}, {-3,8}, {8,-3}
Answer:
x^2 + (x + 2)^2 = 202
x^2 + x^2 + 4x + 4 = 202
2x^2 + 4x + 4 = 202
2x^2 + 4x - 198 = 0
x^2 + 2x - 99 = 0
x = -2/2 ± √((2/2)^2 - (-99))
x = 9 or x = -11
-11 is not a positive number so the number is 9.
Y=4 Because you divide 18 by 4.50 and then just put a point on positive four on your graph.
