The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.
Answer:
it would be 4 because when you put them in number order you would find 4 in the middle of them
Multiply each exponent inside the parentheses by the exponent on the outside:
8^(-5 x -4) / 2^(-2 x -4)
8^20 / 2^8
The answer is C
Answer: 16b
Step-by-step explanation:
distribute
2a+6b+-2a+10b
combine like terms
2a+6b+-2a+10b
(2a+-2a)+(6b+10b)
16b
