Translating the worded problem into mathematical form, the following expression was obtained: ( 8x - 56 / x^2 - 49 ) / (x - 6 / x^2 + 11x + 28)

Simplifying:

( 8x - 56 / x^2 - 49 ) ( <span>x^2 + 11x + 28 / x - 6</span>)

Factoring out:

( 8(x-7) / (x+7)(x-7) ) ( (x+7)(x+4) / x - 6 )

Cancelling out (x-7) and (x+7):

8(x+4) / (x-6)

Therefore, the correct answer is D.

Solve F=D+Drt for t.....
Anuta_ua [19.1K]

Answer:

t = \frac{-D+F}{Dr}

Step-by-step explanation:

Step 1: Flip the equation.

  • Drt + D = F

Step 2: Subtract D from both sides.

  • Drt + D - D = F - D
  • Drt = -D + F

Step 3: Divide both sides by Dr.

  • \frac{Drt}{Dr} = \frac{-D+F}{Dr}
  • t = \frac{-D+F}{Dr}
