Answer:
2.743 × 10^7
Step-by-step explanation:
The reason as to why 10 is to the 7th power is because the number that you turn into scientific notation (27430000), needs to be in ones form. Which is 7 decimal places away.
Answer: the answer is A
Step-by-step explanation:
False because the solution can be positive too
A/b ÷ d/c
a/b * c/d
4x/ x² + 5x -6 * x² + 7x + 6/ x² - 11x + 28 factor
4x/ (x+6)(x-1) * (x+6)(x+1)/ (x-7)(x-4) (x+6) cancels out
4x (x+1) / (x-1)(x-7)(x-4)
Only B is equivalent to 64
26 ≠ 64
24 x 4 is 64 = 64
23 x 42 is 966≠ 64
43≠64
