It would be 1/3rd because your last number would be 4 in the equation of 12 sandwiches.
In order to prove the triangle is a right angled triangle we need to prove that the slope of the lines CA and BC and AB have any negative reciprocals.Lets find the slopes .
AB=(-1,3), (1,2) slope of AB = 2-3/1-(-1)= -1/2 slope of AB is -1/2
BC = (1,2), (-3,1) slope of BC is 1-2/-3-1= -1/-4 slope of BC is 1/4
Slope of CA =(-3,1)(-1,3) slope of 3-1/-1-(-3)=-2/-2=1
Since the slopes do not have any negative reciprocals so the triangle is not a right angled triangle
Answer:
The greatest common factor is 21,
Step-by-step explanation:
Find the prime factors of each term in order to find the greatest common factor (GCF).
3x+6=3(x+2)
3x+6=3x+6
minus 6 both sides
3x=3x
divide by 3
x=x
true
therefor all numbers work for x
there are infinite soltuions
A ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
