Answer:
69
Step-by-step explanation:
by eliminating 20 from 84 we get 64 then add the 3 to get 67 and then we know that we always add 2 to our answers and therefore get 69
let's say is "x", thus "x" is the 100%.
we know that 66 is 150%, what is "x"?
M= -7
M+9=2
M =2-9
M=-7
25y^6 +144
I think this is right :)
