For REAL numbers , anything that makes the sqrt 0 or greater i.e. x >= 6
Just group all of the like terms and you are done
3i+1/2 - 1/3(1-3i)+2 =
3i + 1/2 - 1/3 + i + 2 =
2 1/6 + 4i
Not sure you typed those equations correctly.......please put the question in again.....
2/7 - 1/7 = (2-1)/7 = 1/7 = 1 divided by 7 = .142857
Tangent = opposite / adjacent tangent 75 = 28/x x = 28 / tan75 = 7.50 = ~ 8 feet
Two sides 18 x 13 x 2 =468
Two Ends 1/2 x (12 x 5) x 4= 120
Floor 10 x 18 =180
= 768 sq ft total
No, it's 19
- 1/6 just use the calculator ! is - .1666666666... repeating...
Pretty poor advice !
