Answer 1

thats it

Answer 2

So many posts in one question??

Answer 3

this is what i needed help with it is 30 questions

Answer 4

@jango_IN_DTOWN

Answer 5

@MrNood @mathmale @MattDuhHelper

Answer 6

anyone ?

Answer 7

OK - you are not going to get answers to all those questions

shall we look at number 1 and YOU can do the answer?

Answer 8

In the expression in number 1 start by rewriting it so that all the 'like terms' are together

i.e. all the terms with n^2 then all the terms with n

just re-order the terms until it is in that form, and write the answer here

Answer 9

okay

Answer 10

typo above - it should be
all the terms with m^2 then all the terms with n

Answer 11

7m^2+6.5n-4n+2.5m^2-n

Answer 12

like that ?

Answer 13

is it a ?

Answer 14

that is the original

now move the terms around so that all the terms with m^2 are next to each other
(you can do addition and subtraction in any order - so moving the terms does not change the equation...)

Answer 15

I will not confirm any guesses.

If oyu do not want to do the work to answer these then tell me now...

Answer 16

7m^2+2.5m^2-n+6.5n-4n ?

Answer 17

1. You group the similar terms. Similar terms in the sense, terms whose powers are same.

Answer 18

ok - that is correct

and we can group them like this:
(7m^2+2.5m^2)+(-n+6.5n-4n)

so can you simplify the sums in each bracket?

Answer 19

9.5m^2 ??

Answer 20

9.5n ??

Answer 21

the first answer is correct for tghe first bracket, but the second is wrong

Answer 22

okay is it negative ?

Answer 23

no

(6.5n - 4n - 1n)

Answer 24

OK for someone with 30 questions to tackle you are toooo slow to answer.

This is not the correct place to be if you want 30 answers - it is against the rules to give complete answers here

In fact since this is a preparation for a test there is no right place to be except studying and revising so oyu can answer for yourself
