A. 4.24
B. 4.83
C. 5.75
D. 6.09

Okay, for this I got 5.65? not 5.75? Could someone explain to me how to get the correct answer? I plugged in the numbers to the distance formula: D= sqrt(x2-x1)^2+(y2-y1)^2 and this is what I did: D = sqrt(1-5)^2+(-2-2)^2 = 5.65?

Answer 1

d = sqrt(1-5)^2+(-2-2)^2
d = sqrt(-4)^2 + (-4)^2
d = sqrt(-16+-16)
d = sqrt(-32)
d = sqrt(5.65)

is this right?

@Renee99 Just a heads up, the link doesn't work for outsiders

Answer 3
