Question

(8k+2m^2)/ 25-3 k= -3 m=-3 help[ with explanation

Answer 1

The question is not very clear.  I am giving this answer based on what I understood from your question.

Question asks you to find the value of [(8k + 2m^2)/25] - 3, where k = -3 and m = -3.

Answer is:

Let k = -3 and m = -3.

Then, you have:

[(8k + 2m^2)/25] - 3

= [(8*(-3) + 2*((-3)^2))/25] - 3

= [((-24) + 2*(9))/25] - 3

= [(-24 + 18)/25] - 3

= [(-6)/25] - 3

= - 6/25 - 3

= - 6/25 - 75/25

= - 81/25

Hope this helps.  However, if I am answering the wrong question, please explain the question clearly.
