Answer:
29
Step-by-step explanation:
Since we know that the x-axis is 180 degrees and the square looking symbol represents that it is 90 degrees, we know that the other side has to also equal 90 degrees since 180-90=90.
To find the x, we need to subtract 90 from 61, which would give us 90-61 = 29.
Let Lin be x years old.
Lin = x
Frank = 4x
<span>The difference in their ages is equal to Lin’s age plus 8
</span>⇒4x - x= x + 8
Solve x:
4x - x= x + 8
Combine like terms:
3x = x + 8
Take away x from both sides:
2x = 8
Divide by 2 on both sides:
x = 4
Lin is 4 years old.
Frank is 4 x 4 = 16 years old.
Answer: Lin is 4 years old and Frank is 16 years old.

Answer: Region C</h3>
=============================================================
Explanation:
Check out the screenshot below.
I formed a fourth column where we divide each population over its corresponding area. For example, region A will have a population density of roughly 1312/212 = 6.19 which means there are 6.19 zebras per square km.
The higher the population density, the more competition for resources. We see that region C has the highest density at about 26.24 zebras per square km. There are more zebras competing for food/water/shelter/etc in the same relative area compared to the other regions.
