Question

Compute the distance between (a,b,c) and (-2,5,6).

a.
(a + 2)^2 + (b - 5)^2 + (c - 6)^2
c.
a + b + c -(-2 + 5 + 6)
b.
sqrt((a+2)^2+(b-5)^2+(c-6)^2)
d.
((a + 2) + (b - 5) + (c - 6))^2

Answer 1

B

Explanation:

took it on edge, it's the right answer :)

Answer 2

b. sqrt(a+2)^2+(b-5)^2+(c-6)^2

Explanation:

Use distance formula

sqrt (a-(-2)^2 + (b-5)^2 + (c-6) ^2

sqrt (a+2)^2 +(b+5)^2 + (c-6)^2
