Answer:
False
True
False
False
Step-by-step explanation:
1. We have to get the sum as follows :

= 
= 
= 
= 
So, this is false.
2. We have to get the sum as follows :

= 
= 
= 
= 
So, this is true.
3. We have to get the difference as follows :

= 
= 
= 
= 
So, this is false.
4. We have to get the difference as follows :

= 
= 
= 
= 
So, this is also false. (Answer)

Answer:
The constant of variation for the given quadratic equation is, 30
Step-by-step explanation:
One of the form of a quadratic equation is written as:
....[1]
where k is the coefficient and for this case the constant of variation.
In order to obtain the answer for the given equation, we write the given equation to the form above.
or
or

Comparing this equation with equation [1], to get the value of k;
k=30.
therefore, the constant of variation is, 30.
