6x
42/6 = 7 (valid), 18/6 = 3 (valid), 12/6 = 2 (valid)
7, 8, 9, 10, and 11 are all not divisible by 12, and 12 is not divisible by 18, so 6 is the highest number.
Also, each number has at least one x, so you can take one out.
Remaining=
6x (7 + 3x^2 + 2x^3)
Step-by-step explanation:
prey and predators depends in each other .in the absence of one another is useless or meaning less. predators is responsible for population of prey.if less predators more prey and more predators means less prey.
Answer:

Step-by-step explanation:

To order numbers, they need to all be under the form. So let's transform all this numbers to the decimal form.
3/5 = 0.6
-24% = -24/100 = -0.24
√9 = 3 = 3.0 (all integers are decimals with a zero after the decimal point)
-2 = -2.0
1.6 bar = 1.66666666666 (the bar above the 6 represents an endless number of the digit 6)
π² = 9.86........ endless
(4√5)/2 = 4.47...... endless
4(4/5) = 4 + 4/5 = 4 + 0.8 = 4.8
Now that we got all forms under the decimal form, we can order the numbers from least to greatest:
-2.0 < -0.24 < 0.6 < 1.6666 < 4.47 < 4.8 < 9.86 < 3.0
By correspondence, we get:
-2 < -24% < 3/5 < 1.6 bar < (4√5)/2 < 4(4/5) < π² < 3
Hope this helps! :D
