Answer: She answer 75% correctly
Step-by-step explanation:
150÷200= .75×100
Step-by-step explanation:
x² + 16x + 64 = (x + 8)². Hence p = 8.
Since (x + 8) is a factor of 4x² + 37x + k,
4(-8)² + 37(-8) + k = 0. (by Factor Theorem)
=> 256 - 296 + k = 0
=> k - 40 = 0
=> k = 40.
The value of k is 40.
When multiplying exponents with same base, you would add the numbers that the base is raised to. 8+(-4)=4. So the answer is 5^4, or 625.
Correct me if i'm wrong but i think the best answer choice would be B.
