Answer:
6. Find the product for both sets of polynomials below by multiplying vertically. (4 points: 2 points for each product)
A)
4x^4 - 4x^3 - 16x^2 + 16x
B)
4x^4 - 4x^3 - 16x^2 + 16x
7. Are the two products the same when you multiply them vertically? (1 point)
Yes, the two products are the same when you multiply them.
Making a Decision:
8. Who was right, Emily or Zach? Are the products the same with the three different methods of multiplication? (1 point)
Emily was right, the products are the same with all three different methods of multiplication.
9. Which of these three methods is your preferred method for multiplying polynomials? Why? (1 point)
I prefer the table method because it is easier to understand what is going on, know where and what to do, and it is nicely and neatly laid out in front of me.
When you use the Distributive Property you're really just multiplying the number on the outside by all of the numbers on the inside of the parentheses.
(8 - 3p) (-2) Multiply -2 by 8 and -3p
-2(8) + (-2)(-3p) Multiply
-16 + 6p
A. -5/9 because -5/6 has to have the same denominator as the other number so it has to multiplied by 3, resulting in -15/18. Finally, add 5/18 and -15/18 to get -10/18 and simplify, leading to the final answer of -5/9.
The correct answer for the exercirse shown in the figure attached is the first option, which is: Calculate the area of the circle A and circle B and calculate the difference.
To calculate the area of the circle A and the circle B, you must apply the formula for calculate the area of a circle, which is shown below:
A=πr²
A is the area of the circle.
r is the radius of the circle.
To calculate the difference, you only have to substract the result of the area of the circle A and the area od the circle B:
At=Aa-Ab
