Answer:
Step-by-step explanation:
First, divide by 2 from both sides of equation.
Then, solve.
Subtract by 6 from both sides of equation.
Solve to find the answer.
, which is our answer.
The answer would be x^2-6x-16
Explanation:
y=(x-3)^2 -25
(x-3)(x-3)-25
x^2-3x-3x+9-25
x^2-6x-16
Answer:
D. 119
Step-by-step explanation:
To find the common difference, we take the second term and subtract the first term
2-(-7) = 9
We check by taking the third term and subtracting the second
11-2 = 9
The common difference is 9
The formula for an arithmetic sequence is
an = a1 +d(n-1)
where a1 is the first term, d is the common difference and n is the number of the term in the sequence
a1=-7, d=9 and we are looking for the 15th term so n=15
a15 = -7 +9(15-1)
a15 = -7+9(14)
=-7 +126
= 119
Nothing further can be done with this x=3a
Answer: 3(2 • (2x))
Explanation:
