Answer: -16n-41
Step-by-step explanation:
first, distribute 2 through the parentheses:
<u>2(-n-3)</u>-7(5+2n) = <u>-2n-6</u>-7(5+2n)
second, distribute 7 through the parenthesis:
-2n-6<u>-7(5+2n) </u>= -2n-6<u>-35-14n</u>
Collect like terms:
<u>-2n</u>-6-35 and <u>-16n</u>-6-35
Calculate the difference:
-2n<u>-6-35</u>-14n = -16n-<u>41</u>
SOLUTION:
<u>-16n-41</u>

Answer: 4095
<u>Step-by-step explanation:</u>
He sold 1 car on the first day so the first term (a) is 1. The amount doubles each month so the ratio (r) is 2.
Input those values into the Sum formula:
The theater department sold 102 tickets each night,because 2142÷ 3 nights = 714. 714 ÷ 7=102
In a geometric sequence dividing any term by the term before it yields the common multiplier.
Then x/(x+8) = (3x-8)/x
Solving for x: reduces to x^2-10x +16 factor into (x-2)(x-8)
Then x = 2 or 8
2 produces a sequence of -2, 2, -2 ...
8 produces a sequence of 4, 8, 16 ...
