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.
Answer:
8 Times, Mark would expect to roll a one 'Eight times'
The symmetric property of equality says that if a = b, then b = a.
The associative property for addition merely states that a+(b+c) = (a+b)+c.
The distributive property says that if a, b, and c are real numbers, then
a · (b + c) = (a · b) + (a · c).
The transitive property of equality says that if a = b and b = c, then a = c.
Consider statament: If x + y = z and z = x + 4, then x + y = x + 4. Denote a=x+y, b=z and c=x+4. Now you have if a=b and b=c, then a=c. This is exactly transitive property.
Answer:
k = -1
Step-by-step explanation:
6(5k-8)-20= 11(2k-3)+3k | Given
30k - 48 - 20 = 22k - 33 + 3k | Distribute
30k - 28 = 25k - 33 | Add numbers & combine like-terms
30k = 25k - 5 | Add 28 to both sides
5k = -5 | Subtract 25k from both sides
k = -1 | Divide -5 by 5
Answer:
12+ -2=10?
Step-by-step explanation:
12+-2=10
now add the first number to twice the second number and get 8
12+-2+-2=8
dont know about the other one though
Good Luck!
