Answer: 49
Step-by-step explanation:
The missing constant term in the perfect square is 49.
x^2 + 14x + 49
We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square. 
 
        
             
        
        
        
2/3 are greater and let’s say u have a pie and u cut it up in 3rds and u gave one piece to a friend and u keep the rest u will have more cause it closest to the whole and it just common knowledge
        
             
        
        
        
Remember that the <em>domain</em> is the set of all the x terms.
So in the graph shown here, notice that the x terms seem to be increasing in both a positive and negative direction and there seems to be no limit to how large or how small the x terms can get. So the x terms can be all positive and negative numbers, including decimals and fractions.
In other words, the x terms can be All Real Numbers.
So the domain is equal to the set of all real numbers or <em>R</em>.
The range is the set of all the y terms.
Notice that all the y terms are less than or equal to 9.
So the range is {y: y ≤ 9}.
 
        
             
        
        
        
Using equivalent angles, the solutions are given as follows:

<h3>What are equivalent angles?</h3>
Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant.
For item a, we have to find the equivalent angle on the 2nd quadrant, where the sine is also positive. 
Hence:

Hence  .
.
For item b, if two angles are complementary, the sine of one is the cosine of the other.
Complementary angles add to 90º = 0.5pi, hence:



The equivalent angle on the second quadrant is:

Hence the solutions are:

For item c, the angles are also complementary, hence:



The tangent is also positive on the third quadrant, hence the equivalent angle is:

Hence the solutions are:
