Question

5. Verify a * (b + c) = a × b + ax c, if:
(a) a= -20, b = 15, c = 25
(b) a=-1, b = -2, c = 3
(c) a = 10, b = -2, c = 3
(d) a = -100, b = -200, c = -300​

Answer 1

Answer:

a)

1st part = -20(15+25)

            = -20 x 40

            = -800

2nd part = (-20 x 15) + (-20 x 25)

               = -300 + -500

               = -800
