Answer:
Option C.
Step-by-step explanation:
we have
Solve for x
That means ---> isolate the variable x
Multiply by 8 both sides to remove the fractions
Multiply by -1 both sides
Remember that
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
Divide by 5 both sides
Answer:
C
Step-by-step explanation:
Because it just is
B. (9x^2 + 1)(9x^2 – 1)
C. (3x^2 + 1)^3(3x – 1)
D. (9x^2 + 1)(3x + 1)(3x – 1)
Using this: a²-b²=(a+b)(a-b)
81x^4-1=
(9x²)²-1=
(9x²-1)(9x²+1)= (in the bold half we use the formula again)
(3x+1)(3x-1)(9x²+1)
So the answer is D
Answer: In 1972, there was the highest number of air fatalities occur in which 1210 passengers were killed.
Step-by-step explanation:
Since we have given the table:
With respect to air safety,
In between 1950 and 1976,
The highest number of air fatalities occur in 1972 i.e. 42 which is the highest amongst the all.
The number of passengers were killed in that year = 1210.
Hence, In 1972, there was the highest number of air fatalities occur in which 1210 passengers were killed.
Answer:
Sometimes
Step-by-step explanation:
A Composite number is the number which is not prime except 1. Hence, it has factors other than 1 and itself.
GCF is a greatest common factor i.e. the greatest factor that divides two numbers.
The GCF of two numbers can be composite number.
Example:
GCF of 8 and 24 = 8 which is a composite number.
GCF of 6 and 21 = 3 which is not a composite number.
Thus, GCF two numbers is sometimes a composite number.
