Answer:
Length 37 cm, width 25 cm.
Step-by-step explanation:
Let the original dimensions be length x and width x - 12 cms.
The new dimensions will be length (x - 2) and width (x - 12 - 2) = x-14 cm.
So , from the areas, we have:
x(x - 12) - (x - 2)(x - 14) = 120
x^2 - 12x - (x^2 - 16x + 28) = 120
-12x + 16x - 28 = 120
4x = 148
x = 37 cms
So the length was 37 cm and the width was 37-12 = 25 cm.
25,000 boxes should be ordered
Hope this helps and have a good day :D

Answer:
7.) m = 1/3 ; b = -2.5
8.) m = 2 ; b = 2
Step-by-step explanation:
For m, either do the rise over run method or use 2 points and do (y2-y1)/(x2-x1).
For b, just look at the y-intercept/where it crosses the y axis
I believe those are the right answers but not too sure because the numbers on the graph are a bit blurry so i just assumed it counted by ones.
