Answer: Raspunsul este 4
Step-by-step explanation: 2 * x = x/2 + 6
2* 4 = 4/2 + 6
8 = 2 + 6
Answer:
No, this particular triangle is not a right triangle. See my reasoning, below:
Step-by-step explanation:
We must determine whether the Pythagorean Theorem is satisfied here. Does the sum of the squares of the shorter two sides equal the square of the longest side? Symbolically, does 16^2 + 63^ = 68^2? Does 256 + 3969 = 4624? No.
Answer:False
Step-by-step explanation:
They are the opposite signs of the ones there, so x = 2 and x = -7

Answer:
the sequence is geometric sequence with common ratio (-2).
Option : D is correct.
Step-by-step explanation:
In this question table is given as
n 1 2 3 4 5
f(n) 48 -96 192 -385 768
We have to find out if the sequence is arithmetic or geometric.
For Arithmetic sequence :
Difference should be common in each term of fees.
common difference = f(2) - f(1)
= -96 -48 = -144
similarly = f(3) - f (2) = 192 + 96 = 288
Here, ≠ so the sequence is not an arithmetic sequence.
For Geometric sequence :
Ratio should be common in each term of f(n)
Common ratio =
Therefore, the sequence is geometric sequence with common ratio (-2).
Option : D is correct.
