40, if it's exactly 5x8 and there's no cutting involved. So get at least 48.
5x8=40sq.inches 12x20=2880. sq. inches divide 2880 divided by 40 = 72 pavers
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
5*8 = 40
1x40 2x20 4x10 5x8
1x40 2x20 4x10 5x8
2/5 - 3/8 = (2x8)/(5x8) - (5x3)/(5x8) = 16/40 - 15/40 = 1/40
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
That is 5x8, = 40 .
