Answer 1

Answer:

8. (c)

9. (b)

10. (c)

11. (c)

Step-by-step explanation:

8. It is associative property for addition as it is of the form

   a + (b + c) = (a + b) + c

9. Rational number = -3/4

   Its additive inverse = 3/4

   Therefore, product = -9/16

10. Length of side, a = 52/9 m

     Area of lawn = Area of square = a^2

                                                        = 52/9 × 52/9 = 2704/81 m

11. Let the required number be x.

    Another number = -13/9

     A/Q

     -13x/9 = 1

    x = 9/-13

    x = -9/13

    Thus the number is -9/13.
