Answer:
B: (4x - 7)(16x^2 + 28x + 49)
Step-by-step explanation:
64x^3-343 can be rewritten as 4^3x^3 - 7^3 or (4x)^3 - 7^3. This is the difference of two cubes. The appropriate formula for factoring such is
a^3 - b^3 = (a - b)(a^2 + ab + b^2). Therefore,
our (4x)^3 - 7^3 = (4x - 7)(16x^2 + 28x + 49). This is Answer B.

Log (7/4) is equivalent to log (7.7/4.4), therefore it's log(7.7) - log(4.4), or...
2.0142 - 1.4816 = 0.5326
Answer:
x=11.2426

Answer: 9/10 times
Step-by-step explanation:
Hi, to answer this question we simply have to divide 18/25 by 4/5
Mathematically speaking:
18/25 ÷ 4/5 = (18 x 5) / (25 x 4) = 90/100 = 9/10
In conclusion, the answer is 9/10 times.
