Fx = 2 x + 2 . f − 1 x x = 4 fx=2x+2. f −1 x x=4

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
