Answer:
Step-by-step explanation:
Let the width be w centimeters.
Then the length = w + 7.
The area A is found from the length multiplied by the width.
330 = w(w + 7) = w^2 + 7w.
Now we can rearrange this equation to form a quadratic, as follows:
The factorization of the quadratic is:
(w + 22)(w - 15) = 0
Therefore we find that:
width = 15 centimeters
length = 22 centimeters
Here are the log properties you need:
M = milk
C= cheese
X=meat
milk = 0.5c
meat = 4c
cheese = 1c
<span>4 +0.5 = 1c = 5.5c</span>
C= 42/5.5 = 7.64
X = 7.64 x 4 = 30.56
M =7.64 * 0.5 = 4.67
30.56 + 3.82 + 7.64 = approximately $42
