Consider the three points a = (10, −3,5), b = (0,2,4), and c = (2,1,0) in three-dimensional space.
let be the midpoint of and be the midpoint of .
a. write down the components of the three vectors ab, bc, and ca, and verify through arithmetic that
their sum is zero. also, explain why geometrically we expect this to be the case.
b. write down the components of the vector mn. show that it is parallel to the vector bc and half its
magnitude.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
