Answer:
= 2x²( 2x+ 1) + 2x
or
= 2x (2x² + x + 1)
Step-by-step explanation:
Given in the question two functions,
f ( x ) = 9x³ + 2x² − 5x + 4
g ( x ) = 5x³ − 7 x + 4
To find,
f ( x ) − g ( x )
Substitute each functions
= 9x³ + 2x² − 5x + 4 - ( 5x³ − 7 x + 4 )
Remove parentheses
= 9x³ + 2x² − 5x + 4 - 5x³ + 7 x - 4
Combine like terms and add them up
= 4x³ + 2x² + 2x
Factorise
= 2x²( 2x+ 1) + 2x
or
= 2x (2x² + x + 1)
So the final answer in factored form is 2x²( 2x+ 1) + 2x or 2x (2x² + x + 1)
This can't be further factorise because answer will be in complex numbers
b. 3 must be a factor of a or of b
c. 3 must be a factor of a and of b

Hello there! :)
Vertical angles are congruent, therefore:
∠A ≅ ∠B
3x - 30 = 2x - 9
Subtract 2x from both sides:
3x - 2x - 30 = 2x - 2x - 9
x - 30 = -9
Add 30 to both sides:
x - 30 + 30 = -9 + 30
x = 21.
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, thus
∠ A = ∠ B , substitute values
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21
Answer:
Step-by-step explanation:
Let the first number be x and the second number be y
So, the condition is:
Given that x = 2.3
Dividing both sides by 2.3

C. x+1/11
D. X/11
Answer:
The answer is D.
Step-by-step explanation:
In order to determine the correct sequence, we need to find differences in the numerator and the denominator of the fraction between two continuous terms.
In the numerator, the number is increasing in one digit. The first term in the numerator of the sequense is 1, the second is 2, the third is 3, and so on.
In the denominator, the number is constant (11).
Therefore, we define a "x" variable that represents the number in the numerator. So to find the value of the nth place in the sequence is:
