Answer:
- length: 5.7 yd
- width: 1.7 yd
Step-by-step explanation:
Let w represent the width of the carpet. Then the length is w+4 and the area is ...
w(w +4) = 10
w² +4w = 10 . . . . . eliminate parentheses
w² +4w +4 = 14 . . . . . . add the square of half the w-coefficient to complete the square
(w +2)² = 14 . . . . . . . . . rewrite as a square
w +2 = √14 . . . . . . . . . take the square root
2 = -2 +√14 ≈ 1.7 . . . . yards (width)
Then the length is 4 more yards than this, so is ...
length = 1.7 +4 = 5.7 . . . yards
The length and width are 5.7 and 1.7 yards, respectively.
_____
In the attached graph, we let x represent the length. As you can see, the magnitudes of the two zeros are width and length.
Answer:
Volume of room will be left after Michael stores the boxes 426 feet cube
Step-by-step explanation:
It is given that
Michael is putting 12 boxes in a storage shed.
Each box is in the shape of a rectangular prism with dimensions 1.5 feet by 1.5 feet by 2 feet.
If the storage shed has dimensions 6 feet by 10 feet by 8 feet,
<u>To find the volume of one box
</u>
Volume = 1.5 x 1.5 x 2= 4.5 feet cube
Volume of 12 such box = 4.5 x 12 =54 feet cube
<u>To find the volume of shed
</u>
Volume of Shed = 6 x 10 x 8 =480
<u>
To find remaining portion of shed</u>
Volume of room will be left after Michael stores the boxes =volume of shed - volume of box
=480 - 54 = 426 feet cube
