x^2 = 800. Take the square root of each side.
x = √(800) and -√(800)
$2.50
Hope this helps!
May I have brainliest? :D
Step-by-step explanation:
6k + 12 + 9=9
6k + 12 = 9 - 9
6k + 12 = 0
12 = -6k
12/-6 = -6k/-6
2/-1 = k
k = -2
We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:

Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:

On plotting the series, the result will be like this:
Answer:
x = 30
Step-by-step explanation:
4x + 2x = 180
6x = 180
x = 30
