The difference between the two polynomials is 11x²3y³ - 4xy².
<h3>What is the Difference between the Polynomials?</h3>
The difference between two polynomials is the result you get by subtracting one from the other.
Thus:
= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)
= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y
= 11x²3y³ - 4xy²

Answer:
The total amount she will pay after taxes is $339.58
Step-by-step explanation:
The Total cost of the speaker plus tax = $349
The tax rate applied = 2.7%
Tax payable = $349 * 2.7% = $9.423
The tax amount on the speaker is Tricia = $9.423
Thus, the total amount she will pay after taxes (i.e. paying $9.423) for purchase of the Speaker will be = $349 - $9.423 = $339.58.
The original price of the speaker excluding tax is $339.58.
Answer:
1. 2:5
2. 110 (the total degree of a triangle is 180 so it would be 40+30+x=180)
3. 37 (It's a right angle, 90 degrees so it would be 90-53=x)
