Help me I’m going a math test :))) will mark brainliest

D) 4034.4

Step-by-step explanation:

47 * 3 = 141

158 * 3 = 474

Perimeter=

141+141+474+474

= 1230 total fencing

Price=

1230 * 3.74=

D) 4034.4

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

this is not possible to solve with the info given.   you need at least an one angle somewhere.
