a corner of a cube connects 3 sides to each other,
then add the side of the cut
so it would have 4 sides
To do this multiply 1 by 4, then 3 by 5. 4 over 15 is your answer.
<span>I can be wrong, but I think that the answer is: To find the values of p, q, r and s, you should start by finding all factor pairs of the leading coefficiant and constant term. </span>
Yes its right
hope this helps
