Answer:

(x-3) is the factor of polynomial x2 + 6x + 9

and it's zero is -3

Step-by-step explanation:

by solving it we get ;

=

x {}^{2}  + 6x + 9

=

x {}^{2}  + 3x + 3x + 9

=

x(x + 3) + 3(x + 3)

=

(x + 3) {}^{2}

now, equating it with 0, we get

=

(x + 3) {}^{2}  = 0

=

x + 3 = 0

=

x =  - 3

so, the factor is ( x + 3 )

bekas [8.4K]

Answer:

The total amount due at the register will be: $65.09    

Step-by-step explanation:

The cost of an item = $61

tax on item = 6.7%

The tax amount =  6.7% × 61

                           = 0.067 × 61

                           = $ 4.09

The total cost = cost of an item + tax amount

                           = $61 + $4.09

                           = $65.09

Therefore, the total amount due at the register will be: $65.09
