Answer:
sqrt(-1) = i
Step-by-step explanation:
The square root of -1 is the imaginary number i
sqrt(-1) = i
Answer:
5/7
Step-by-step explanation:
In order to multiply fractions, multiply the numerators together and multiply the denominators together - the answers will be the numerators and denominators of the product, respectively. Also, remember that 5 can also be expressed as 
in fraction form since it is a whole number.
Knowing this, multiply like so:
·
Therefore, 5/7 is the answer.
2+2=4
You start with 2 and add an additional 2 to that. You now have 4.
I hope that helps!!!!!!

We can’t really see the problem
Move the -2x^2 over to the other side to make it positive and then rewrite in descending order of x's. Like this: 2x^2 - 12X + 18. Factor out a 2 to make things easier: 2(x^2 - 6x + 9). Now factor what's inside the parenthesis. Both signs are the same and they're both negative: (x - )(x - ). It's up to us now to find out what goes inside there with those x's. What adds up to -6 has to multiply to +9. Two 3's fit inside there perfectly: -3-3=-6, and -3*-3=9, so the factors are (x-3)(x-3), and setting those equal to zero according to the Zero Product Property, x-3=0 so x = 3 with a multiplicity of 2.
