Choose an equation that would be used to solve 0 = -x2 + 10x – 8

Below

Step-by-step explanation:

You can use the quadratic formula:

x =  [-10 ± √(10^2 - 4*-1* -8)] / -2

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
