The unit price of the 20 pack is $0.79 and the unit price for the 8 pack is $0.80.

Step-by-step explanation:

Simply Take the price of the pack of batteries divided by the number within the pack.

$6.40 / 8 == $0.80

$15.80 / 20 == $0.79

Cheers.

$8x^2+18x+9= \frac{1}{2}(16x^2+(4*9)x+18)=\frac{1}{2}(4x+6)(4x+3) \\= \frac{1}{2}(2)(2x+3)(4x+3)=(2x+3)(4x+3)$
