Answer: 10x³
<u>Step-by-step explanation:</u>
n=0 1
n=1 1 2 1
n=2 1 3 3 1
n=3 1 4 6 4 1
n=4 1 5 10 10 5 1
The second term of the expansion is: 5(a)³(b)
= 5(x)³(2)
= 10x³
Answer c
Step-by-step explanation:
Answer and Step-by-step explanation:
The answer is H.

When 4 is brought to the power of a number it gets multiplied to the numerator of 1/3. When inputting those numbers for x in this function, the result is what is shown on the table, meaning the function is correct.

Answer:
x ∈ [-2, 7]
Step-by-step explanation:
The given equation ...
x^2 -5x -4 ≤ 10
can be rewritten as ...
x^2 -5x -14 ≤ 0
and factored as ...
(x +2)(x -7) ≤ 0
Clearly, the "or equal to" condition will be met when x=-2 and x=7. For values of x between these numbers, one factor is negative and the other is positive. Hence the product will be negative. So, numbers in that interval are the solution set.
x ∈ [-2, 7]
