Given:

Expanding using double angle formula,

Rearranging into a single equation,

Combining like terms,

Now multiplying each term by -1,

Factor greatest common factors out,

Applying Zero property rule,

<h3>
<u>{</u> <u>For sin(x) = 0</u></h3>
• Solve the trignometric equation to find a particular solution,


• Find the union of the solution sets,

<h3>
<u>{</u> <u>For</u><u> </u><u>2</u><u> </u><u>sin</u><u>(</u><u>x</u><u>)</u><u> </u><u>-</u><u> </u><u>1</u><u> </u><u>=</u><u> </u><u>0</u> ,</h3>
• Rearrange unknown terms to the left side,

• Divide both sides of the equation by the coefficient of variable,

• Solve the trignometric equation to find a particular solution,


}
☆ Now finding the union of both sets

Hence, the answer is 
Answer:
'n plus 5 squared' is n + 25
Step-by-step explanation:
Note that "five squared" is 5^2, or 25.
Then 'n plus 5 squared' is n + 25.
You combine like terms
Example: 5x^3+3x+1-4x^3-2x-1
The answer would be x^3+x
4. It cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.
5. The relationship in Tuesday's table can be described by a constant unit rate.
<h3>What is a Constant Unit rate Relationship?</h3>
A constant unit rate relationship can be described as a relationship between two input and output variables, x and y, in such a way that, k = y/x. "k" is the constant of proportionality of the relationship or the unit rate between the two variables.
4. We have the following:
5/20 = 1/4
10/40 = 1/4
12/60 = 1/5
14/80 = 7/40
16/100 = 4/25
Thus, this cannot be a constant or unit rate relationship because the value of k = y/x vary across table values.
5. 4/20 = 1/5
8/40 = 1/5
12/60 = 1/5
16/80 = 1/5
20/100 = 1/5
Thus, the value of k is the same across all table values, therefore, the relationship in Tuesday's table can be described by a constant unit rate.
