Answer:
20 5/6 ft
Step-by-step explanation:
5 3/5 = 28/5
1 4/5 = 9/5
V = l * w * h
210 = l * 28/5 * 9/5
210 = l * 252/25
multiply both sides by 25/252
5250/25 = l
Reduce
20 5/6 = l
20 5/6 ft
1)Find all the like terms=3x3x/6>1/3x+2
2)Multiply both sides by six=9x>2x+12
3)Move the variables to the left side and change the sign=9x-2x>12
4)Find the like terms=7x>12
5)Divide by sides by seven=x>12/7
6)Your answer is x>12/7
I hope this helps! :)
Remark
You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen
Solution
let y = x^2
x^4 = x^2 * x^2
x^4 = y * y
x^4 = y^2
Now the expression becomes
y^2 + 8 y - 9 = z
(y + 9)(y - 1) = z
Now put the x^2 back in.
(x^2 + 9) ( x^2 - 1) = z
x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.
Answer
(x^2 + 9) (x + 1)(x - 1)
