Simplify completely quantity 2 x squared plus 13 x plus 20 all over x squared minus 5 x minus 36 .

adoni [48]

Answer:

(2x + 5)/(x - 9)
3. quantity 2 x plus 5 over x minus 9

Step-by-step explanation:

Quantity 2 x squared plus 13 x plus 20 all over x squared minus 5 x minus 36

(2x² + 13x + 20)/(x² -5x - 36) =
(2x²+ 5x + 8x + 20)/(x² - 9x + 4x -36)=
(2x + 5)(x + 4)/(x - 9)(x + 4) =
(2x + 5)/(x - 9)

Correct option is option 3

If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(–2)?

Vedmedyk [2.9K]

F(x) = 8 - 10x

g(x) = 5x + 4

Finding (fg)(-2).

First let us find fg(x), this is the same as f(g(x))

f(g(x))

f(5x + 4)

Recall, f(x) = 8 - 10x, therefore f(5x + 4) would be such that anywhere we see x in the f(x), we replace it with 5x + 4

f(x) = 8 - 10x

f(5x +4) = 8 - 10(5x + 4)

   = 8 - 50x - 40

   = -50x + 8 - 40

   = -50x - 32

f(g(x)) = fg(x) = -50x - 32

fg(-2) = -50*(-2) - 32 = 100 - 32 = 68

Therefore fg(-2) = 68

I hope this helped.
