The steeper the line is (the larger the slope), the faster the speed is. This is due to the fact that speed=distance/time and the slope=y/x which is distance over time on a distance v time graph.
let me know if you need further explanation by leaving a comment and I hope this helps.

Define length and width
---------------------------------------------------------------------------------
Let the width be x
Width = x
Length = 3x
---------------------------------------------------------------------------------
Form equation and solve for x
---------------------------------------------------------------------------------
x(3x) = 48
3x² = 48
x² = 48 ÷ 3
x² = 16
x = √16
x = 4
---------------------------------------------------------------------------------
Find length and width
---------------------------------------------------------------------------------
Width = x = 4
Length = 3x = 3(4) = 12
---------------------------------------------------------------------------------
Answer: Width = 4cm, Length = 12cm
---------------------------------------------------------------------------------
X+(y+z) is equal to saying (x+y)+z
This is called the cumulative property when order doesn’t matter or doesn’t change the equation. As in 1+2 is the same as 2+1. No matter which way we get the same answer. This only works with multiplication and addition though. Hope this helps. Any questions please just ask!! Thank you so much!!
65+56=121, 180-121=59, 59/8=7.375 , so the answer is A
