Answer 1

Yes, exactly.

Answer 2

2m^2 + 3m- 7 - (3m^3 +7m +12)

Answer 3

Could you please show me the process

Answer 4

I can do this just give me some time

Answer 5

distribute the minus sign, then collect like terms. what do you get?

Answer 6

It's long an d confusing

Answer 7

Yes first distribute minus then

Answer 8

Answer 9

then add like terms

Answer 10

3m^3 +7m +12 to get the sum of 2m^2 + 3m- 7

Arrange,

3m^3 + 2m^2 + 3m + 7m + 12 - 7

Now add terms with same variables and their expoents.

3m^3 + 2m^2 + 10m + 5

Answer 11

Cool Saif you are a legend

Answer 12

Thanks Anikate! =)

Answer 13

yw

Answer 14

np

Answer 15

Yes but when we add 3m^3 and 3m^3, it becomes 6m^3, but there is not m^3 in the answer

Answer 16

u didnt wrote any 3m^3 in the second thing.

Answer 17

No, the question goes like this: 3m^3 +7m +12 + (BLANK) = 2m^2 + 3m- 7 ?

Answer 18

-3m^3 + 2m^2 - 4m -19

Answer 19

What money bird said..

Answer 20

Actually u have to solve it this way,
like u have:

2 + x = 5

And u have to find that "x"

So for that u have to solve for x.

x = 5 - 2
x =3

Answer 21

And moneybird how did you get that?

Answer 22

2m^2 + 3m- 7 - (3m^3 +7m +12)

Answer 23

Now,

Apply the same example here,

3m^3 +7m +12 + (BLANK) = 2m^2 + 3m- 7

U have to solve for the "blank"

"Blank" = (2m^2 + 3m - 7) - (3m^3 + 7m + 12)

Answer 24

unfathomable^

Answer 25

so the supposed answer minus the first question

Answer 26
