Add together -9x and -11x to get the value of X. Add together 4y and 7y to get the value of Y.
Answer:
4a+5a+7b-b
the first thing is to put the like terms together
Step-by-step explanation:
then add or subtract as given after pairing.
Therefore;
our answer is; 9a+6b
since it is factorisable we can further write it this way; 3(3a+2b)
q2) 6c+4d-c-7d
we first put the like terms together
6c-c+4d-7d
we then add and subtract
5c-3d
since our answer is not factorisable we leavem;
5c-3d as our final answer
Answer:
1
Step-by-step explanation:
(5c-3)(-5c+7)
Answer = -25c2+50c-21
