Here are the answers to the given questions above. The sets of numbers that are closed under multiplication are the following: Whole numbers, and Integers. The answers would be options A and D. Whole numbers are closed<span> only </span>under<span> addition and </span>multiplication. Integers are closed under<span> addition, subtraction, </span>multiplication<span>, and division (with the exception of division by 0). Hope this answer helps.</span>
I assume the equation is
then let 
.
The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us
Then
but again we omit the negative solution, so that
Answer:
2.0
Step-by-step explanation:
Subtract the smaller number from the larger to find their difference:
1.5 -(-0.5) = 2.0
The distance between the given values is 2.0.
2 is the answer because when you subtract 4 from 6 you get 2
So for this trinomial, I will be factoring by grouping. Firstly, what two terms have a product of 16x^2 and a sum of 10x? That would be 8x and 2x. Replace 10x with 2x + 8x:
Next, factor x^2 + 2x and 8x + 16 separately. Make sure that they have the same quantity inside the parentheses: 
<u>Now you can rewrite this as 
, which is your final answer.</u>
