<span>a³-b³=(a-b)(a²+ab+b²)
64x⁶ - 27
64 = 4³,
x⁶ = (x²)³
27 = 3³
</span>64x⁶ - 27 = 4³(x²)³ -3³ = (4x²)³ -3³. Now, we can use a formula where a=4x², b=3
(4x²)³ -3³ = (4x² -3)((4x²)² +4x²*3 + 3²) = (4x² -3)(16x⁴ +12x² + 9)

Answer: </span>64x⁶ - 27= (4x² -3)(16x⁴ +12x² + 9) <span>

Answer:
The third one.
Step-by-step explanation:
Because all the other ones does a transformation that doesn't change the size of the figure. The third one is dilated, which means that the original figure is being made smaller or bigger. So the final result will be different from the original figure.
The answer is $2.50 because you do 145-132.50=12.5
Then you divide by 5 because that’s the difference between students then the final answer is 2.50
Step-by-step explanation:
since
25⁰= 1 minute
x⁰ = 11 minutes
cross multiply
25 x 11= x
x= 275⁰
temperature after being turned on=275⁰
temperature after 11 minutes= 275⁰ + 75⁰= 350⁰
temperature(x) after being turned on
25tt=x
temperature (x) after minutes
x= 25tt + 75⁰
