If ( pq ) and ( qr ) are both true statements, then it follows that both ( p ) and ( q ) must be true (since ( pq ) is true) and both ( q ) and ( r ) must be true (since ( qr ) is true). Consequently, this implies that ( q ) is true in both cases. However, we cannot definitively conclude the truth values of ( p ) or ( r ) without additional information. Thus, the statements themselves do not inherently guarantee the truth of ( p ) or ( r ) alone.
2 + pq

False. In order for the line PQ to lie in plane B, then both P and Q must lie in plane B.
It means "premium quality". It is not an official form of grading.

QPR is congruent to SPR PR is perpendicular to QPS PQ =~ QR PT =~ RT

p(q + r) = pq + pr is an example of the distributive property.
PQ ST
If you are working with real numbers, or even complex numbers, pq is the same as qp, so the result is the same as 2pq. If you use some multiplication that is NOT commutative (such as, when you multiply matrices), you can't simplify the expression.
False. In order for the line PQ to lie in plane B, then both P and Q must lie in plane B.
