The 4/$5 dollar because you save a more when you should have spend $6 the other answer you don’t really save.
Taking out the greatest common factor
GCF of 40, 40 and 32 = 8
GCF of n^4, n^3 and n^3 is n^3
so the factors are
8n^3(5nm^2 +5m^3 - 4)
10
because you would do 35 divided by 7 which is 5.
5 x 2 is 10
I believe it has 8 angles, each are 135 degrees
sorry if its wrong
