Answer:
Step-by-step explanation:
Our equations are

Let us understand the term Discriminant of a quadratic equation and its properties
Discriminant is denoted by D and its formula is

Where
a= the coefficient of the 
b= the coefficient of 
c = constant term
Properties of D: If D
i) D=0 , One real root
ii) D>0 , Two real roots
iii) D<0 , no real root
Hence in the given quadratic equations , we will find the values of D Discriminant and evaluate our answer accordingly .
Let us start with

Hence we have two real roots for this equation.


Hence we do not have any real root for this quadratic

Hence D>0 and thus we have two real roots for this equation.

Hence we have one real root to this quadratic equation.
<h3>Whats your question?</h3>
Our function is:

Now, if
is a factor of
then
must satisfy the equation:
So, 
Putting 
We get,




So, the value of 'a' for the given expression is 1281.
Answer:
The answer is <u>8</u>.
Step-by-step explanation:
Given:
4d - 35= -3.
Now, the solution:

Adding both sides by 35 we get:


Dividing both sides by 4 we get:

Therefore, the answer is 8.
360-150-150=60 arc ac=60, the measure of arc is same as central angle and inscribe angle is half of central angle so answer is 30
