You have to find LCD (lowest common denominator) in this case it will be
:
Answer: C
Answer:
= 4n + 3
Step-by-step explanation:
Note there is a common difference d between consecutive terms, that is
d = 11 - 7 = 15 - 11 = 19 - 15 = 4
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 4, thus
= 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
The answer is D. j - 14 = 28
Basically, saying the answer aloud, you will be saying the jellybeans my mom added to the bag minus the 14 jellybeans I had previously is equal to my total of 28 jellybeans I have now.
