Answer:

Hansen can feed his mutt 2 cups of dog food per day for 7 days.

Step-by-step explanation:

(2 cups)/(day) is the rate at which the dog eats. After how many days will the 14 cups of dog food be gone?  Write and solve a suitable equation:

 

  2 cups                            

--------------- * d = 14 cups,

     1 day

or

   1                             7

--------- * d      =       -------

1 day                          1

Multiplying both sides of this equation by (1 day) yields d = 7 days

Hansen can feed his mutt 2 cups of dog food per day for 7 days.

The length of a rectangular floor is 4 feet longer than its width w. The area of the floor is 525 ft^2.
andre [41]

Answer:

  • 525 = (w+4)(w)
  • 21 ft by 25 ft

Step-by-step explanation:

Let w represent the width of the floor. Then the length of the floor is (w+4) and its area is ...

  A = LW

  525 = (w+4)(w)

  w^2 +4w -525 = 0

  (w -21)(w +25) = 0 . . . . factor the above

Solutions are ...

  w = 21, w = -25

We are interested in the positive solution: w = 21.

The floor is 21 feet wide and 25 feet long.

_____

<em>Alternate solution</em>

Sometimes, when the factors aren't obvious, it works well to write an equation for the average of the dimensions. Here, we can represent that with x, and use (x-2) for the width, and (x+2) for the length. Then we have ...

  525 = (x-2)(x+2) = x^2 -4

  529 = x^2

  √529 = 23 = x

Then w=23 -2 = 21, and the length is w+4 = 25.
