2b^2. This is because you have a positive a^2 and a negative so they cross it one another so it just leaves the b’s.
$4.30X40%=1.72
4.30-1.72=2.58
2.58X6%=.15
2.58+.15=2.73
Final price: $2.73
A) 2(3x+5x+1)=2(8x+1)=16x+2
b)16*6+2=98
c)(9x+3)*10x/2=(9x+3)*5x=45x^2+15x
d)45*6^2+15*6=1710
e)45x^2+15x-3x(5x+1)=45x^2+15x-15x^2-3x=30x^2+12x
