Answer:
<h2>A. a^14 divided by -4</h2>
Step-by-step explanation:

Answer:
let the third side be x
Using pythagoras theorem we get,
(58)^2 = (42)^2 + (x)^2
3364=1764+x^2
x^2=3364-1764
x^2= 1600
x=√(1,600)
x=40
4x^5+2x-1 would be an example, fifth dregree means the highest exponent is 5. hope this helps.
According to PEMDAS, the parentheses would go first.
3+1 = 2
42/2=21
Hope this helps!
