Answer:
10
Step-by-step explanation:
distance formula = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}
(x_1, y_1) = (5, 1)
(x_2, y_2) = (-3, -5)
\sqrt{ [(-3) - (5)]^2 + [(-5) - (1)]^2 }
\sqrt{ [-8]^2 + [-6]^2 }
\sqrt{ 64 + 36 }
\sqrt{ 100 }
= 10
Answer:
C
Step-by-step explanation:
7+5 makes 12 which is the same as 3+4+5 which is 12
Answer:
3√15
Step-by-step explanation:
x=y
x^2+x^2 = 9*30
2x^2 = 270
x^2 = 9*15
x = y = 3√15
If y=15 then x=45 because 45 minus 15 is 30
