P varies partly as q and partly as the square of r. When p=6,q=8 r=4 and when p=10,q=12 and r=5. find the formula connecting p,q and r

6 answers

p = mq + nr^2
so,
8m + 16n = 6
12m + 25n = 10

Now just solve for m,n
I don't understand the explanation
I don't understand
I understand well
I understand not
So what is M and N now
