If -1<x<0, which of the following expressions is the largest? A.-1 B.x C. 2x D.x^3
Cerrena [4.2K]
The answer is C-2x because you can substitute a number between -1 and 0 for x, so for example .5, and try out all the choices with .5. Ultimately you get 2(.5) as the largest number, so the answer is C.

Answer:

1). x = 10 m

2). x = 15 cm

3). x = 5 yd

4). AB = 10 units

Step-by-step explanation:

1). By Pythagoras theorem in the given triangle,

 a² + b² = c²

 Where 'c' = Hypotenuse

 a and b = Legs of the right triangle

 By substituting measures of the sides in the formula,

 x² = 8² + 6²

 x = \sqrt{100}

 x = 10 m

2). By using Pythagoras theorem in this triangle,

  x² = 9² + (12)²

  x² = 81 + 144

  x = \sqrt{225}

  x = 15 cm

3). By Pythagoras theorem,

  (13)² = x² + (12)²  

  169 = x² + 144

  169 - 144 = x²

  25 = x²

  x = 5 yd

4). If BD is a perpendicular bisector of AC,

  AD = CD = 6 cm

  By Pythagoras theorem in ΔABD,

  AB² = BD² + AD²

  AB² = 8² + 6²

  AB = \sqrt{100}

  AB = 10 units

   2 (6) + 5 (3)

   12 + 15

   = 27

b) a = 3 + 3

   a = 6

c) 3(2a+1) - 6a + 7 = 10

   6a + 3 - 6a + 7 = 10

   3 + 7 = 10
