Answer:
C.
Step-by-step explanation:
The answer is C, as as any value of m will make the equation true.
Such as if we used 2 as a substite value for m.

Lets simplify both equations:


Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.
Answer:
0.54 lillies per square meter.
Step-by-step explanation:
First we <u>calculate the area</u>:
Area = length * width
Area = 6 m * 4 m = 24 m²
The we <em>divide the population of lillies (13) by the area</em>, to <u>calculate the population density</u>:
13 lillies / 24 m² = 0.54 lillies/m²
So the population density is 0.54 lillies per square meter.
Number of person not wearing red: 54 - 18 = 36
