Answer:
Step-by-step explanation:
The formula for calculate the Area of a rectangle is:
Where "l" is the lenght and "w" is the width.
And the formula for calculate the peimeter of a rectangle is:
Where "l" is the lenght and "w" is the width.
We know that the perimeter of the rectangular baking sheet is 58 inches and its area is 201.25 in². Then:
<u>The steps are:</u>
1. Solve for the "l" from the formula :
2. Substitute into the formula
and solve for "w":
Applying the Quadratic formula , we get:
3. Substitute into
:
4. Substitute into
:
Therefore, since the value of the lenght of a rectangle must be greater that the value of the width, we can conclude that the lenght and the width of the rectangular baking sheet are:
Answer:
y = 36x
Step-by-step explanation:
Given that y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x = , thus
k = =
= 36
y = 36x ← equation of variation
