Can someone simplify these for me?: 4(2x+3y)
5(4a+4b)
8(4a-b)
7(x+y)
10(6x-5y)
6(3 x -2x)
3(10a-5b)
11(2a+11b)

Thanks :)​

i agree because i see the other persons thinking is clear

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
