<h3>What is a quadratic equation?</h3>
A quadratic equation is an algebraic equation where the highest power of 
is 2. The general form of a quadratic equation is as follows:
,
where <em>a</em>, <em>b</em>, and <em>c</em> represent known constants, and is the unknown.
In this question, if you take a look at the second option, you will see that it is possible to rearrange the equation to make it look the general form:
⇒ 
Therefore, this equation is quadratic.
The other three options are not quadratic equations because none of them have an 
term in them.

Answer:
volume of cone=1/3 πr²h=1/3 ×π×5²×15=125πcm³
Answer:
is correct
Step-by-step explanation:
A) profit/original price x100 =percentage profit
(Profit: 360-300=$60)
=60/300 x100
=20%
b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720
Profit without discount: 720-600= $120
120-100= $20 discount
20/720 x100 =2.78%
