Answer is the last choice
2a-4/1= -a-1/a-4
Cross multiply
(2a-4)(a-4)= -(a-1)
2a^2-8a-4a+16= -a+1
Bring right to left sign change signs
2a^2-8a-4a+16+a-1=0
Combine like terms
2a^2-11a+15=0
a= 2 b= -11 c= 15
Use quadratic formula
-b+-sq rt of b^2-4ac. Divided by 2a
-(-11) +- 11^2-4(2)(15) divided by 2(2)
11+-sq rt 121-120 divided by 4
11+1 /4. 11-1/4
12/4. 10/4
3. , 5/2

Step-by-step explanation:
Given data:
stocked of crayfish 
in 1000 gallon water tank
size of tank = 3 ft deep and 6 feet diameter
let radius of tank is r and height of tank is h m
Total stocked of crayfish is
![= 20[ 2\pi r(r+h) ft^2]](https://tex.z-dn.net/?f=%20%20%3D%2020%5B%202%5Cpi%20r%28r%2Bh%29%20ft%5E2%5D)
[1 ft = 0.3048 m]
= 315.2
