Question

Find the product using suitable properties :

a) 125 ×(-35) +(-125)×65
b) (-21)×(120)​

Answer 1

Step-by-step explanation:

a) 125×(-35) + (-125)×65

= 125×(-35) + 125×(-65)

= 125 × {-35 + (-65)}

= 125 × (- 100)

= -12500

b) (-21) × 120

= (- 20 - 1) × (100 + 20)

= -20(100 + 20) - 1(100 + 20)

= -2000 - 400 -100 -20

= -2280
