The equation used for this is

=
if you knew n then we could solve this equation
So the factors are
79=2*5*7
100=2*2*5*5
2*5 is common to both so that is the greatest common factor (10)
10 is the answer
Answer:
x^2-4x+y^2+6y-108=0
Step-by-step explanation:

Answer:
1.) -4x+30y 2.) distributive property 3.) -4x+30y, (-0.4(3)+3(2)), 10(-1,2)+10(6), -12+60, =48
Step-by-step explanation:
10(-0.4x+3y)= 10(-0.4x)+10(3y)= -4x+30y
10(-0.4(3)+3(2))
10(-0.4(3))+10(3(2))
10(-1.2)+10(6)
-12+60
= 48
It is important to understand the meaning of orthocenter in respect to a triangle first. Ii is actually the intersection of all the altitudes within a triangle. The altitudes can be drawn from an angle to the opposite side but the line should create a right angle with the side of the triangle. In case of obtuse triangle, the three lines would meet outside the triangle. I hope the answer helps.
