Question

3. Verify that (a + b) = C # a = (b + c) for a = -225, b = 15 and c = -3.
(4) Verify that a = (b + c) = (a + b) + (a + c) for
(i) a = -10, b = 1 and c = 1
(ii) a = 12, b = 1 and c = -2​

Answer 1

Step-by-step explanation:

$4) \: \: (b + c) = (a + b)(a + c) \\ 1 + 1 = ( - 10 + 1) +( - 10 + 1) \\ 2 = - 9 +( - 9) \\ 2 = - 18 \\ so \: it \: not \: follow \: the \: rule \\ no2 \\ 1 - 2 = 12 + 1 + 12 - 2 \\ - 1 = 23 \\ it \: is \: not \: follow \: the \: rule$
