Answer:
d
Step-by-step explanation:
Since 20% is taken off, 100%-20% or 80% remains.
80% of $65 is 0.80�$65 or $52. That's the price without tax.
The tax on $52 is 0.06�$52 or $3.12,
$52 + $3.12 = $55.12
D.) 8x^2+11x-9
5x^2 -(-3x^2) =8x^2
7x -(-4x) =11x
-4 -5 =-9

A(X)= 2πRH+2πR^2
A(X)=2π(7.5)(8)+2π(7.5)^2=730.42 = 730
