Evaluate the expression when m= -2 m^2 +9 m+ 3

Can someone help me understand how to solve these ?

im not positive but i think if im wrong then tell me

Step-by-step explanation:

Solution :

mn + m + n + 1

= m( n + 1 ) + 1( n + 1 )

= ( n + 1 )( m + 1 )

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

where did you get them? if you picked from the grass, is is probably poisonous.
