Sqrt(6x-24) = x - 4
6x - 24 = (x - 4)^2
x^2 - 14x + 16 = 0
x=10 / x=4
Which of the following is an arithmetic sequence? a.2,4,16,32 b.2,3,7,1, c.3,0,-3,-6 d.5,-5,5,-5
Lelechka [254]
D. 5,-5,5,-5
because the others don't follow a constant pattern
2n² + n + 1
<u>Explanation:</u>
The sequence is 4, 11, 22, 37
Difference between: 7, 11, 15
The first differences are 7, 11, 15, and the second differences are 4.
Since half of 4 is 2, then the first term will be 2n^2.
Subtracting 2n² from the sequence gives 2, 3, 4, 5 which has nth term n + 1.
Therefore the final answer is 2n² + n + 1
Answer:
-1
Step-by-step explanation:
Simplify the following:
x - 2/2 - x
Hint: | Reduce (-2)/2 to lowest terms. Start by finding the GCD of -2 and 2.
The gcd of -2 and 2 is 2, so (-2)/2 = (2 (-1))/(2×1) = 2/2×-1 = -1:
x + -1 - x
Hint: | Group like terms in x - 1 - x.
Grouping like terms, x - 1 - x = (x - x) - 1:
(x - x) - 1
Hint: | Look for the difference of two identical terms.
x - x = 0:
Answer: -1
Answer:
96
Step-by-step explanation:
25% is 1/4 of 100%
thus, if you multiply 24x4 you get 100%
