Answer:
The length of the other would be 36.
Step-by-step explanation:
a² + b² = c²
b² = c² - a²
b² = 60² - 48²
b² = 3600 - 2304
b² = 1296
√b² = √1296
b = 36
All you need to do is plug -5 into the second equation and you see it is near (-5, -8). When plugged into the top, you get (-5, -27/4) which comes out to ABOUT -6.75 for the Y value. The closest is actually a tie. The first option is .8 from the first and .45 from the second leading in a total distance of 1.25. The second, which is the fellow answer, is 1.2 from the first and .05 from the second, leading to 1.25 away.
The third, which is next closest is 1.8 from the first and .55 from the second leading to a distance of over 2 from the optimal, so only the first two are answers.
For this case we must indicate an expression equivalent to:

For properties of powers we have to:

So, the above expression can be rewritten as:

Thus, the resulting expression is: 
Answer:

Option D
5/21 expressed as a decimal is D 0.238095
I believe it is the last option, but pleae don’t come for me if you get it incorrect. But if that is the case, I apologize in advance for any inconveniences this may cause.
Kind regards!
