A brainliest would help tons! :D
So, we are given the following equation...
(5m-2n)/p^2
But we are given a heads up that m=8, n=4, and p=-2.
So that changes the equation to the following...
(58-24)/-2^2
Remove unneeded parentheses.
Our new equation is 58-24/-2^2
Subtract 58 from 24.
58-24=34.
Find -2^2
-2^2=-4
Now, we divide 34 by -4 and we get -8.5
-8.5 is your final answer!
If this helped please mark me as brainliest!
