Answer & Explanation

1.2

  1. x^2 + 5x – 4x – 20 = 0

(x – 4) (x + 5) = 0

x = 4, – 5

 

  1. y^2 + 8y + 5y + 40 = 0

(y + 8) (y + 5) = 0

y = –8, – 5

x >= y

 

2.5

  1. x^2 – 6x – 5x + 30 = 0

(x – 5) (x – 6) = 0

x = 5, 6

 

  1. y^2 – 8y – 5y + 40 = 0

(y – 8) (y – 5) = 0

y = 8, 5

No relationship between ‘x’ and ‘y’ exits.

 

  1. 3;
  2. (x + 5)^2 = 0

x = –5

 

  1. (√5y – √3)^2 = 0

x = √3/√5

 

  1. 5
  2. 10x^2 – 35x + 6x – 21 = 0

(5x + 3) (2x – 7) = 0

x = -3/5, 7/2

 

  1. y^2 + 17y – 4y – 68 = 0

(y – 4) (y + 17) = 0

y = 4, –17

No relationship between x and y exists.

 

  1. 1;

 

  1. 4

 

  1. 3

 

  1. 2

? = 46.81

 

  1. 1

? = (3 + √27)(53√27) – 159√27

= 159√27 + 53 * 27 – 159√27 = 1431

 

  1. 5

? = 8.5/100 * 160 – 0.42/100 * 750

= 13.6 – 3.15 = 10.45
