Answer:

Step-by-step explanation:
The given parabola has equation

We rewrite in standard form to obtain:


Split the middle terms to get:

Factor by grouping:



Start with

Add 2x to both sides:

Subtract 21 from both sides:

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

So, the answer is 
the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.
Answer:
The expression x2y - 2xy - 24y can be factored by first factoring out a common factor of y.
