Question

The sum of mn + (5 – 2) and mn+3 is​

Answer 1

Answer:

(mn+3).

= (mn+5-2) + (mn+3)

= (mn+3) + (mn+3)

= mn+3+mn+3

= 2mn+6

Thus, the addition of (mn+5-2) and (mn+3), we get 2mn+6.

Now, we will subtract (mn+5-2) and (mn+3), we get

= (mn+5-2) - (mn+3)

= (mn+3) - (mn+3)

= mn+3-mn-3

= 0

Cancelling the similar terms, we get 0.

Thus, subtraction of (mn+5-2) and (mn+3) is 0.

Answer 2

Answer:

Step-by-step explanation:

mn + ( 5 - 2) + mn + 3

= mn  + ( 3 ) + mn +3

= 2 ( mn + 3 )

        (or)

= 2mn + 6
