<h2>Hello!</h2>
The answer is:
The rewritten expression is:
<h2>Why?</h2>
To solve this problem we need to use the trigonometric identity of the double angle for the cosine which states that:
Also, if we want to rewrite only with terms of cos(x) and sin(x), we can apply the following property:
So, rewriting the trigonometric equation, we have:
Then, we are given the expression:
Now, rewriting the given expression with only sin(x) and cos(x), we have:
Hence, the answer is:
Have a nice day!
Answer:
The pair of shoes equal 18.
The boat equals 3
The chair equals 4
Step-by-step explanation:
Let x = shoes
You found the palm trees!
So the top picture would be
18 + x = 2x Subtract x from both sides
18 = x We found the value of the shoes.
Let's go so the last picture. We now know the shoes.
Let x = the boat now
18 = 6x Divide both sides by 6
x = 3 We found the value of the boat.
Finally, let's look at the second picture.
Let x = the chair now
3 + x = 7 Subtract 3 from both sides
x = 4 We found the value of the chair.
