A = 3 + (x + 2)
c=7+(x+4)
B = 4+ (x - 2)
D = 10 + (2x-7)

1.=x+5

2.=x+11

3.=x+2

4.=2x+3

Step-by-step explanation:

3+x+2

=3+x+2

=(x)+(3+2)

=x+5

7+x+4

=7+x+4

=(x)+(7+4)

=x+11

$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
