PLZ HELPP Write the sum using summation notation, assuming the suggested pattern continues. -3 + 6 + 15 + 24 + ... + 132 a) summation of negative 27 times n from n equals 0 to infinity b) summation of negative 27 times n from n equals 0 to 15 c) summation of the quantity negative 3 plus 9 n from n equals 0 to infinity d) summation of the quantity negative 3 plus 9 n from n equals 0 to 15

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

$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
