Answer:
6 : 5
Step-by-step explanation:
The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...
3L = <em>l</em> = 4W
L/W = 4/3
Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...
<em>l</em> = 4(3) = 3(4) = 12
<em>w</em> = 3+3+4 = 10
Then the ratio <em>l </em>: <em>w</em> is 12 : 10 = 6 : 5.
Ax^2+bx+c=0 is the standard form, so we add 5 to both sides to get
1*x^2+(-10)x+21=0
