Answer:
18.3 cm
Step-by-step explanation:
So tallest tree = 279.7 cm
So shortest tree = 261.4 cm
So difference = 279.7 - 261.4 = 18.3 cm
Line Q's equation would be y=1/2x+3 and line S's equation is Y=1/2x-2. You would compare them. So you would get 1/2x+3=1/2X-2. Subtract 1/2X from both sides and you get 3=-2. So the answer is these lines have no solution.
Yea that can be a good equation. I had this question last year and my teacher said it was ok.
But it can be wrong, I don't really know. Cuz we don't go to the same school.
