Question

Simplify m3 + m3 And Simplify 10+3c+5d-7c+d

Answer 1

For this case we must simplify the following expressions:

$m ^ 3 + m ^ 3\\10 + 3c + 5d-7c + d$

Expression 1:

$m ^ 3 + m ^ 3 =$

They are similar terms so we can add.

$2m ^ 3$

Expression 2:

$10 + 3c + 5d-7c + d =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

$10 + 3c-7c + 5d + d =\\10-4c + 6d$

Answer:

$m ^ 3 + m ^ 3 = 2m ^ 3\\10 + 3c + 5d-7c + d = 10-4c + 6d$
