2 and 3/5 boxes because 1/5 + 2/5 = 3/5, and 2 + 3/5 = 2 and 3/5
Yes, any number that you can divide 72 by without creating an irrational number answer is a factor of 72. Therefore, since when we divide 72 by 2, we get 36, which is a whole number and therefore satisfies the criteria.

Step-by-step explanation:
Given expression:
Answer:
A
Step-by-step explanation:
Begin with Euler's formula. I am assuming youre aware of this if youre taking complex algebra? You can prove Euler's formula by doing a Maclaurin expansion of cosine, sine, and e^x. Euler's formula states that:
We can put the first complex number in exponetial form by noticing the input is 2pi/3. The second complex number has an input of pi/3. Therefore:
Then:
Simplify the coefficients to get:
When you divide exponentials, you subtract the exponents. Therefore:
Put it back into trigonemtric form using Euler's formula:
Cosine of pi/3 is 0.5, and sine of pi/3 is square root of 3 over 2. We have:
