Answer:

n = 18

Step-by-step explanation:

N = variable

Equation: 3n - 18 = 2n

Solve:

3n - 18 = 2n

3n = 2n + 18                          Add 18 to both sides

3n - 2n = 18                          Subtract 2n from both sides

n = 18

Hope this helps,

I NEED HELP WITH PRECALC PLEASE
alisha [4.7K]

Answer: First question: D, Second question: A

Step-by-step explanation:

Note: I'm not so good at expanding so I'll just solve it :)

So this leaves either C or D

Apply the sum rule:

8-70=-62

The only one that gives a negative sum is D

For the second picture, the one you have chosen is correct

a1 = 3 and r = -5 so:

an = 3/5 * (-5)^n

Plugging in 8 for n (the first choice) we get the given term: -234,375
