6 is added to itself z many times whilst z is multiplied by itself 6 times.
Answer:
30
Step-by-step explanation:
Note that, when two negative signs are directly next to each other, they mean addition. Note the rule:
A positive sign & A positive sign = Positive number.
A positive sign & A negative sign = Negative number.
A negative sign & A negative sign = Positive number.
In this case:
- (-15) = + 15
Simplify. Combine like terms:
15 + 15 = 30
30 is your answer.

25%
There are 4 different numbers you could draw. Having all 4 cards would be equal to 100%, making each card worth 25%.
25 + 25 + 25 + 25= 100
The first thing you should do is to determine all the zeros, and you will have 7, -11, 2 + 6i, 2 - 6i.
After that you have to <span>subtract and (x) from every each zero that you have above, which means
</span>

<span>And the last step is to multiply them together, and that's all you need!

<span>The volume of each celluloid die is (.25 x .25 x .25) = 0.015625 cubic inch.
To manufacture 24,000 of them, you need to start with <u>at least</u>
(24,000) x (0.015625) = <u>375 cubic inches</u>.
I don't know how celluloid is sold, so you should also keep in mind that
375 cubic inches = about 207.8 fluid ounces, or about 6.5 quarts.
I'm sure a bit more than that was used in the manufacture, since
there's always some wasted, spilled, or trimmed off of the edges. </span>
