Answer:
$34.20
Step-by-step explanation:
First, find the cost with tax
You are paying 7.2% tax, but you are also paying for 100% of the bill
100%+7.2%=107.2%
So, you are really paying for 107.2% of the bill
Convert 107.2% to a decimal by dividing by 100 or moving the decimal 2 spaces to the right
107.2/100=1.072
Multiply the decimal by the cost of the bill
1.072*45.90=49.2048
But, we also have a coupon for $15 off
Subtract 15 from the cost with tax
49.2048-15=34.2048
Round to the nearest cent/hundreth
$34.20
Hope this helps! :)

Answer:
x = 3 + √6 ; x = 3 - √6 ; 
; 
Step-by-step explanation:
Relation given in the question:
(x² − 6x +3)(2x² − 4x − 7) = 0
Now,
for the above relation to be true the following condition must be followed:
Either (x² − 6x +3) = 0 ............(1)
or
(2x² − 4x − 7) = 0 ..........(2)
now considering the equation (1)
(x² − 6x +3) = 0
the roots can be found out as:
for the equation ax² + bx + c = 0
thus,
the roots are
or
or
and, x = 
or
and, x = 
or
x = 3 + √6 and x = 3 - √6
similarly for (2x² − 4x − 7) = 0.
we have
the roots are
or
or
and, x = 
or
and, x = 
or
and, x = 
or
and,
Hence, the possible roots are
x = 3 + √6 ; x = 3 - √6 ; ;
The expression that can be used to represent x is not shown.
x is the price of the shoes
5% commission on every pair of shoes sold. $1.00 is the value of the commission received.
$1/5% = 1 / 0.05 = 20
The price of the shoes is 20.
6x^3 + 5y^3 + 7y
So the third option.
