Answer:
Step-by-ste
Oh, oh! This is such a tricky question...
Guess what!
Both of them are correct. Why?
Because if we simplify 3/12, we get 1/4th!
(How do you simplify?)
3/12 = 1/4
Because if we divide both "3" and "12" in 3/12 by 3, we get 1 instead of 3 and 4 instead of 12.
I hope you've got it! ;)
slope m = - 2 → B
calculate m using the ' gradient formula '
m = (y₂ - y₁)/(x₂ - x₁)
choosing 2 'clear ' coordinates from the graph of the line
(x₁, y₁) = (0, 7) and (x₂, y₂) = (7, - 5
) =
= - 2
m =
First triangle side lengths: 9, 4, 8
First triangle perimeter: 21
Second triangle side lengths: 18, 8, 16
Second triangle perimeter: 42

200 - (2x) = 42
200 - 42 = 2x
158/2 = 2x/2
x = 79
