3x +4 is 7x and 4x- 1 is 3x because yhat how you solve that
Answer:
The length is 22.5 and the width is 19.5
Step-by-step explanation:
2L + 2W = P
\/
2L + 2W = 84
\/
W + 3 + W + 3 + W + W= 84
\/
4W + 6 = 84
\/
4W = 78
\/
W = 19.5 L = 19.5 + 3 = 22.5
I hope this helps, have a nice day! :D
Answer:
3.5 is the correct answer
volume of the box is 675 cubic inches
A machine produces open boxes using square sheets of plastic.
It is a square sheet so length and width are same
Lets assume length as x so width is also x
The machine cuts equal-sized squares measuring 3 inches on a side from each corner of the sheet.
After turning up the sides the height of the box becomes 3 inches
We know the volume of a box formula
Volume = Length * width * height
We know length is x , width is x and height = 3
So V = x * x * 3
Given volume = 675 cubic inches


Divide by 3 on both sides

Now we take square root on both sides
x = 15
the length of one side of the open box is 15 inches.
