Answer 2

Step-by-step explanation:

Heya!!

Question : Verify the following

a) (-25) x [ (-7) + (-15)] = [ (-25) x (-7)] + [ (-25) x (-15)]

Solution :

• First we will solve the brackets then will do the other operations.

=> (-25) x [ -7 - 15] = 175 + 375

=> (-25) x (-22) = 550

=> 550 = 550

Hence, Verified.

550 = 550

b) (-7) x [(-8) + 9] = [-7 x (-8)] + [(-7) x 9]

• In this case also, first we will solve within the brackets then will further perform other operations.

=> (-7) x [-8+9] = [7 x 8] + [-7 x 9]

=> (-7) x 1 = 56 + [-63]

=> -7 = 56 - 63

=> -7 = -7

Hence, Verified

-7 = -7
