Answer:

  • C. x < -1 or 1 < x < 9/5

Step-by-step explanation:

  • 2/(x - 1) > 7/(x + 1)
  • [7(x - 1) - 2(x + 1)]/(x - 1)(x + 1) < 0
  • (7x - 7 - 2x - 2) / (x - 1)(x + 1) < 0
  • (5x - 9) / (x - 1)(x + 1) < 0

<u>Zero's in the ascending order:</u>

  • x = -1, x = 1, x = 9/5

<u>Negative intervals:</u>

  • x < -1, 1 < x < 9/5

Correct choice is C

Tanya has a garden with a trench around it. The garden is a rectangle with length 2.5m and width 2m. The trench and the garden t
Drupady [299]

Answer:

5.5m^2

the area of just the trench is 5.5 m^2

Step-by-step explanation:

The Area of trench only is the total area(trench and garden) minus the Area of garden

Area of trench only = total area(trench and garden) - Area of garden

Area = length × breadth

Substituting the given dimensions;

Total area = 3.5 × 3 = 10.5 m^2

Area of garden = 2.5×2 = 5 m^2

Area of trench only = 10.5 m^2 - 5 m^2

Area of trench only = 5.5m^2

the area of just the trench is 5.5 m^2
