The result of multiplying the polynomials is (2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12
<h3>How to multiply the
polynomials?</h3>
The polynomial expression is given as
(2x + 3) (-x + 2y - 4)
Expand the brackets in the above polynomial expression
So, we have
(2x + 3) (-x + 2y - 4) = 2x * (-x + 2y - 4) + 3 * (-x + 2y - 4)
Open the brackets in the above polynomial expression
So, we have
(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 8x + -3x + 6y - 12
Evaluate the like terms in the above polynomial expression
So, we have
(2x + 3) (-x + 2y - 4) = -2x² + 4xy - 11x + 6y - 12
Hence, the solution is -2x² + 4xy - 11x + 6y - 12

Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
Answer:
17.1 liters
Step-by-step explanation:
Since one gallon equals 3.8 liters.
We can multiply 4.5 gallons by the approx. 3.8 liters
4.5 * 3.8 = 17.1 liters
