Every single one of those expressions factor.  When factored, this is what we have: \frac{(3x-7)(x+3)}{(x+3)(x-2)} * \frac{(2x-7)(x+9)}{(3x-7)(2x+7)}.  After canceling out like factors, what we are left with is this: \frac{1x+9}{1x-2}.  That means that b = 9, c = 1, and d = -2

pqrs is a rectangle with sides ps=5cm and pq =12cm find the length of qr ,sr and the two diagonals pr and qs. ​
never [62]
<h3>Given:</h3>

PQRS is a rectangle.

PS = 5cm

PQ = 12cm

<h3>To Find:</h3>

The length of qr ,sr and the two diagonals pr and qs.

<h3>Solution:</h3>

Opposite sides of a rectangle are equal.

QR = PS = 5cm

SR = PQ = 12cm

By using Pythagoras Theorem, we get

PR = √PS^2 + SR^2

or, PR = √25 + 144

or, PR = √169

or, PR = 13cm

Diagonals of a rectangle are equal.

QS = PR = 13cm

<h2>Answer:</h2>

QR = 5 cm

SR = 12 cm

PR = 13 cm

QS = 13 cm
