An integer P is added to another integer Q, then the result is R. If R is -12 more than P, then find Q. Also find R when P is 42.

The positive integers p ,q ,&r are all primes if p^2-q^2=r , then find all possible values of r

One metre long metallic wire is broken into two unequal parts P and Q. The part P is uniformly extended into another wire R. Find the ratio of the resistances of P and R and also the ratio of the lengths P and Q.

1 meter long metallic wire is broken into two unequal parts P and Q P part of the wire in uniformly extended into another wire R . Length of R is twice the length of P and the resistance of R is equal to that of Q . Find the ratio of the resistance P and R and also the ratio of the length P and Q

A 2m long metallic wire is broken into two unequal points P and Q. P part of the wire is uniformly extended into another wire R. Length of R is twice the length of P and resistance of R is equal to that of Q. Find the ratio of resistances of P and R and also the ratio of lengths of P and Q.

The positive integers p,q,&r are all primes if p^(2)-q^(2)=r, then find all possible values of r

The positive integers p,q and r are all primes if p^(2)-q^(2)=r, then find all possible values of r.

The positive integers p,q, and r are all primes if p^(2)-q^(2)=r, then find all possible values of r.

If p, q and r are integers, is pq+r even? (1) p+r is even. (2) q+r is odd.
