Answer:A. -1.11x^2+ 3.74+ 10.64
Step-by-step explanation:
a. p. e. x. (just took the test)
Standard form is a+bi where a and b are real numbers
remeber that i²=-1
ok
we got to get the i out of the denomenator
remember the differnce of 2 perfect squares where (a-b)(a+b)=a²-b²
so multiply the whole thing by
we get
in standard form, it is
N= numerator
D= denominator
N:D ==> 2:3
2:3, 4:6, 6:9... And so on...
The pattern here is that the numerator increases by 2 and the denominator by 3. Easy right?
Now 5 is added to the "n".
Now it is N:D ==> 3:2
3:2, 6:4, 9:6... And so on...
The pattern here is inverted then the 2:3 one.
If I'm right then which one (you might have to continue the process/pattern) then one of them will increase by 5.
3 => 2 = +1 (2+1=3)
6 => 4 = +2 (4+2=6)
9 => 6 = +3 (6+3=9)
12 => 8 = +4 (8+4=12)
15 => 10 = +5 (10+5=15)
18 => 12= +6 (12+6=18)
Q. Which one is +5?
A. 15:10
That is what "I" think it is.
Now, the question is,
Does it work? Does it fit the above description?
Q. Does it even work? Does it fit the above description?
I would say b
hope it helped!
