<em>In order to increase the area of a rectangular garden that measures 12 feet by 14 feet by 50% Jake must increase each dimension by equal lengths, x:</em>

<h2>
Explanation:</h2><h2 />
First of all, let's calculate the area of the original rectangular garden:

Jake wants to increase the area by 50%, so the new area would be:

He wants to increase the area by 50% and plans to increase each dimension by equal lengths, x, so this is represented by the figure below, therefore:

Step-by-step explanation:
1minute=2lap
30lap=30/2
=15minutes
4 and -2.5
You can get this by first factoring the equation.
(2x + 5)(x - 4)
Then set both equal to zero and solve individually.
3/4 - 3/10
Convert to like denominators:
15/20 - 6/20
Subtract the numerators:
9/20
