Yes you are correct very nice job!
Answer:
D). irrational numbers
Step-by-step explanation:
The irrational numbers are the set of number which can NOT be written as a ratio (fraction). Decimals which never end nor repeat are irrational numbers. Irrational numbers are "not closed" under addition, subtraction, multiplication or division.
Rewrite and factor 9 and 21;
3•3+3•7= 3(3+7)
GCF for 9 and 21 is 3
Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.
- i =

- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:

<u>Your answer is 5i√2, or the second option.</u>
