Hi!
Tip #1: To multiply polynomials, consider the variables separate from the numbers.
So we are multiplying 2xyz * -4x²yz
Let's start by multiplying the variables.
xyz * x²yz
Tip #2: The exponents tell you how many of each variable there are. When multiplying variables, add the exponents. When a variable does not seem to have an exponent, that means there is an invisible exponent of 1! (x =
)
xyz * x²yz = (x + x²)(y + y)(z + z) = x³y²z²
Now multiply the numbers! (just like normal)
2 * -4 = -8
Now combine the numbers with the variables once again.
-8x³y²z²
The answer for 2xyz * -4x²yz is -8x³y²z²
Hope this helps! :)
Answer: C (2, 12), (3, 6), (4, 16), (5, 25)
Explanation:
C has a consistent slope and the y-values never repeat.
A and E have repeating y-values.
B’s slope is not consistent.
6.05,6.5,13.3,13.4 let me know if this helps
It would be C. Because PEMDAS. Division goes first in this equation. So it’d be 15 divided by 3 plus 6
