If a ray QT bisects ∠RQS, what would be the measure of one of the resulting angles? The PS is line segment. Q is the point between segments PS. QR is another line segment passes through segment PS. The angle PQR is (3x - 5) degree and angle SQR is (x + 1) degree.

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.

Ron has 8 caps and 4 of his caps are blue. thes rest of his cap are red. how many of ron's caps are red

(fog)(x) if f(x)=x^2- 4 and g(x)=x^2 + 2 x, f(g(x))= f(x^2+2x) (x^2+2x)^2-4 (x^2+2x)(x^2+2x)-4 (x^4+2x^3+5x+4x^2)-4 x^4+2x^3+4x^2+5x-4 what am i doing wrong
