D the typical ostrich runs at a speed of about 36 mph
U work this out by adding all number together then diving by number of results
So total of results = 360
360/10 results = 36
Answer:
The solution is -5 or 11
Step-by-step explanation:
We are given the equation;

We are supposed to solve the equation;
Taking 5 to the other side;


Dividing both sides by 4


We can cube both sides;


Then we can get the fourth root on both sides of the equation;
![\sqrt[4]{ (3-x)^4} =\sqrt[4]{4096}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%20%283-x%29%5E4%7D%20%3D%5Csqrt%5B4%5D%7B4096%7D)
We get;

Solving for x

Therefore;

Therefore, the solution is -5 or 11
