Question

2. Verify (-22) x [(-4) + (-5)] = [(-22) × (-4)] + [(-22) (-5)​

Answer 1

Step-by-step explanation:

L.H.S

(-22) × [ (-4) + (-5) ]

=> (-22) × (-9)

=> 198

R.H.S

[ (-22) × (-4) ] + [ (-22) × (-5) ]

=> 88 + 110

=> 198

Since 198 = 198, therefore L.H.S = R.H.S

∴ (-22) × [ (-4) + (-5) ] = [ (-22) × (-4) ] + [ (-22) × (-5) ]

This is known as the distributive property of multiplication over addition.

=> a × (b + c) = (a ×  b) + (a ×  c)

Hope this helps!
