If rx – st = r, which expression represents r.

statuscvo [17]

Answer:

${ \tt{rx - st = r}}$

» Collect like terms, r terms on the left hand side by subtracting r from both sides and adding st to both sides

${ \tt{(rx - st) { \green{ - r + st }} = r{ \green{ - r + st}}}} \\ { \tt{rx - r = st}}$

» On the left hand side, factorise out r

${ \tt{ \green{r(x - 1)} = st}} \\ \\ { \boxed{ \tt{ \blue{ \: r = \frac{st}{x - 1} }}}}$

Finger [1]

Using the slip and slide method:

2x^2+5x-12
x^2+5x-24
(x+8)(x-3)

(x+8/2)(x-3/2)
(x+4)(2x-3)

Final answer: (2x-3)(x+4)
