Question

Verify that a + ( b + c) = (a + b) + c , a = (-12) , b = 4 , c = (-25)

please i need the steps also

Answer 1

Step-by-step explanation:

given, a+(b+c)=(a+b)+c.

1. -12{4+(-25)}=(-12+4)-25
2. -12(4 - 25) = (-8)-25
3. -12 - 21 = (-33)
4. -33 = (-33)
5. LHS = RHS
6. so,it is verified

Answer 2

Given:

• a = -12
• b = 4
• c = -25

To verify:

a + (b + c) = (a + b) + c

In other words, this property is also known as ‘Associate property of Addition’

Solution:

First consider the Left Hand Side.

a + (b + c)

= -12 + (4 - 25)

= -12 + (-21)

= -12 - 21

= -33

Now simplify Right Hand Side.

(a + b) + c

= (-12 + 4) - 25

= (-8) - 25

= -8 - 25

= -33

As it can be seen,

LHS = RHS

★ Hence Verified ★

KNOW MORE:

There are some more important properties which are listed below:

• Commutative property

(a + b) = (b + a)

• Distributive property

(a × b) + (a × c) = a × (b + c)
