Answer:
the total price of the CD including tax is $11.984
Step-by-step explanation:
The computation of the total price of the CD including tax is shown below:
The Selling price of the CD is $14
CD is 20% off
And, the sales tax rate is 7%
So, the total price of the CD is
= ($14 - $14 × 20%) × (1.07)
= $11.2 × 1.07
= $11.984
Hence, the total price of the CD including tax is $11.984
The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²
<h3>What is an Expression ?</h3>
An expression is a mathematical statement which has variables , constants and mathematical operators simultaneously.
The expression given in the question is
(3x+6y)(3x+6y) and (4x+9y)(4x+9y)
the difference when (3x+6y)(3x+6y) is subtracted from (4x+9y)(4x+9y)
(4x+9y)(4x+9y) - (3x+6y)(3x+6y)
16 x² + 36xy+36xy +81y²-9x²-18x -18x -36y²
7x² +36xy+45y²
Therefore in simplest term , The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²
