Answer:
25 in by 47 in
Step-by-step explanation:
The volume of the box is the product of the dimensions of the base and the depth of the box.
The base width will be 22 inches less than y.
The base length will be 22 inches less than (y+22).
The depth of the box will be 11 inches.
(You might want to get a piece of paper, cut squares from the corners, and fold it up to see how this works.)
Then the volume in cubic inches is ...
V = LWH
825 = (y in)(y -22)(11)
Dividing by 11 and writing this quadratic in standard form gives you ...
y² -22y -75 = 0
(y -25)(y+3) = 0 . . . . factor the equation
y = 25 or -3 . . . . . only the positive solution is useful here
The original dimensions (in inches) are y and y+22, so for y=25, the original dimensions are ...

<h3>Henry drove the truck for 208 miles</h3>
<em><u>Solution:</u></em>
Given that,
Base fee = $ 18.95
Additional charge of $.79 for each mile driven
Let "x" be the miles driven
Henry had to pay $183.27 when he returned the truck
Therefore,
Cost for rent = base fee + charge for "x" miles
183.27 = 18.95 + 0.79x
0.79x = 183.27 - 18.95
0.79x = 164.32
Divide both sides by 0.79
x = 208
Thus Henry drove for 208 miles the truck
Answer:not this 18x3+19x2-20x+21
Step-by-step explanation:
Answer:
4 because 5 times 4 is 20 and 3 times 4 is 12
2+2-2*2/2 divide 2/2=
2+2-2*1 multiply 2*1=
2+2-2 add 2+2=
4-2 subtract 4-2=
2
answer= 2
