Answer:

Step-by-step explanation:
Given that,
...(1)
We need to find the value of
.
Put n = 1 to find the first term.

Put n = 2 to find the second term.

Put n = 3 to find the third term.

Put n = 10 to find the tenth term.

It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :

We have, n = 10, a = 5 and 
So,

So, the value of
is equal to 280.
Answer:
y = -1/3x + 2
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals.
The line y = 3x - 2 has slope 3.
The perpendicular line has slope -1/3.
Now we find the equation of the line that has slope -1/3 and passes through (-9, 5).
y = mx + b
y = -1/3x + b
5 = (-1/3)(-9) + b
5 = 3 + b
b = 2
The equation of the perpendicular is
y = -1/3x + 2
Answer:
-26
Step-by-step explanation:
2 is 14 away from -12. The other number that is 14 away from -12 is -26.
-12 + x = 2
x = 14
-12 - 14 = -26
Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.
We can use the FOIL method.
(3b - 5c)(3x + 5y)
6bx + 15by - 10cx - 25cy
There are no like terms, so that expression is our final answer.
