Answer:
-9, 15
Step-by-step explanation:
Subtract 7 and multiply by 4
1/4 |2x-6| +7 = 13
1/4 |2x -6| = 6
|2x -6| = 24
2x -6 = ± 24
2x = 6 ±24
x = 3 ±12
x = -9, 15
_____
For graphing purposes, it is often convenient to rewrite the equation so the solutions are where the function is zero. Here, we can do that by subtracting 13 from the equation.
(1/4 |2x -6| +7) -13 = 0
that seems right to me, I think. maybe something like that to double check
The range of possible values for the volume of the boxes would be 1200 - 1800 cubic inches
The dimensions of the rectangular cardboard boxes are given as
Case I
Length = 20 inches
breadth = 15 inches
Height = 4 inches
Volume of the rectangular cardboard box in case I = Length x breadth x breadth
= 20 x 15 x 4
= 1200 cubic inches
Similarly,
Case II
Length = 20 inches
breadth = 15 inches
Height = 6 inches
Volume of the rectangular cardboard box in case I = Length x breadth x breadth
= 20 x 15 x 6
= 1800 cubic inches
