Answer:
6
Step-by-step explanation:
I am not completely sure.
3x
if x=4 then it would be 12
if x=6 then it would be 18
if x=9 then it would be 27
if x=10 then it would be 30
the side is shorter than 19 but definitely longer than 6. To me, it looks like a little more than double, more of triple and 6 times 3 is 18.
Answer: 50m
Step-by-step explanation:
"Combinations" isn't really the right word, because a combination doesn't take order of elements into account, and the outcome of a race certainly does depend on order. "Permutations" would be the correct term.
If 4 students are competing, then the race has
4! = 4 • 3 • 2 • 1 = 24
possible outcomes.
Answer:
Step-by-step explanation:
Refer the attached figure .
We are given a line AB
Point A
Point B
Formula for slope 'm' when two points are given :
Substituting thew values
Since we are given that AB is perpendicular to BC
So, By property - perpendicular slopes are negative reciprocals of each other.
So, Slope for line BC : 
Point B = (4,4)
Formula of equation of line : 
Hence the equation of line BC :
90 counterclockwise hope I’m right
