Question

Find the product using suitable properties. please answer me fast please. with full explanation please. 30x(-65)+(-65)x(-49)​

Answer 1

Answer:

30x(-65)+(-65)x(-49) = 1235....

Step-by-step explanation:

By taking (-65) as common

= (-65) × [30+(-49)]

= (-65) × [30-49]

= (-65) × -[-30+49]

= (-65) × -[49-30]

= (-65) × -19

= 65×19

= 1235

Hope it helps you

Answer 2

Step-by-step explanation:

Given that:-

30x(-65)+(-65)x(-49)

It is in the form of (a×b)+(a×c)

Here, a=-65 ; b=30; c=-49

(-65)×[(30+(-49)]

This is in the form of a×(b+c) It is known as Distributive Property under multiplication over addition

=>(-65)×(30-49)

=>(-65)×(-19)

=>1235

30x(-65)+(-65)x(-49)=1235

Used concept:-

If a,b,c are three numbers then (a×b)+(a×c)=a×(b+c) is called Distributive property under multiplication over addition
