Question

(ii) Is (-15) [(-7)+(-1)] =(-15) * (-7).+ (-15) * (-1)?​

Answer 1

Answer:

True.

Step-by-step explanation:

By using distributive property , the number outside the bracket (-15) is multiplied with the first integer of the bracket (-7) and then with the second (-1) . And as there is a sign in between the numbers in the brackets , the sign will sit in the expression .

Lets now see if both of them answer the same thing.

-15 [(-7) + (-1) ] = -15 * (-8) = 120

-15 * (-7) + (-15) * (-1) = 105 + 15 = 120.

Therefore , it is true .
