Well first you have to know what i is. i is the sqrt of -1 so try doing 3+5(sqrt-1)/1+sqrt-1. I don't know how to solve it though sorry
Answer:
4. D
5. A
Step-by-step explanation:
For #4, I first divided 15 by 4 and saw what the greatest whole number it was divisiable by. Then I wrote the remain as a fraction
For #5, I first multiplied by 4*6 and then add 5 to that answer
Solution
The dimension of the rectangular floor is 18ft long and 12 ft wide
Using the conversion table
It is given that 1yd =3 ft
This shows that
12 feet will be equivalent to

Also 18ft will be equialent to

Therefore the new dimension is 6 yard by 4 yard
The area will be

Therefore the required area is
Three numbers between 3.65 and 3.66 could be:
1) 3.651
2) 3.655
3) 3.657
4) 3.659
Hope this helps! :)
