Answer:
x = (i sqrt(7))/4 - 3/4 or x = -(i sqrt(7))/4 - 3/4
Step-by-step explanation:
Solve for x:
x - 1 - 2/x = 3 x + 2
Bring x - 1 - 2/x together using the common denominator x:
(x^2 - x - 2)/x = 3 x + 2
Multiply both sides by x:
x^2 - x - 2 = x (3 x + 2)
Expand out terms of the right hand side:
x^2 - x - 2 = 3 x^2 + 2 x
Subtract 3 x^2 + 2 x from both sides:
-2 x^2 - 3 x - 2 = 0
Divide both sides by -2:
x^2 + (3 x)/2 + 1 = 0
Subtract 1 from both sides:
x^2 + (3 x)/2 = -1
Add 9/16 to both sides:
x^2 + (3 x)/2 + 9/16 = -7/16
Write the left hand side as a square:
(x + 3/4)^2 = -7/16
Take the square root of both sides:
x + 3/4 = (i sqrt(7))/4 or x + 3/4 = -(i sqrt(7))/4
Subtract 3/4 from both sides:
x = (i sqrt(7))/4 - 3/4 or x + 3/4 = -(i sqrt(7))/4
Subtract 3/4 from both sides:
Answer: x = (i sqrt(7))/4 - 3/4 or x = -(i sqrt(7))/4 - 3/4

btw that my actual answer. it really long.
Answer:
84 ft or 84.474
Step-by-step explanation:
46.93 ft/sec * 1.8 sec = 84 ft
Explanation:
The reason you can use simple multiplication is because of the units:
46.93
f
t/
sec
⋅ 1.8
sec would equal 84.474 f
t
⋅
sec/
sec
however the seconds cancel out, leaving you with just the distance traveled.
The reason the answer is 84 instead of 84.474 is because the number 1.8 only contains two significant figures
Hey love thanks for reposting this so we can see it better! i hope this answers your question if it doesn't let me know se i can better help you understand. Thank you! have a wonderful day and good luck in this class you can do it just keep trying! :)
