Step-by-step explanation:
lets take a look....
In order to find the perimeter of a triangle you have to get the sum of all sides. In other words,
Blue triangle:

Red triangle:

Difference:

First, we are going to find the common ratio of our geometric sequence using the formula:

. For our sequence, we can infer that

and

. So lets replace those values in our formula:


Now that we have the common ratio, lets find the explicit formula of our sequence. To do that we are going to use the formula:

. We know that

; we also know for our previous calculation that

. So lets replace those values in our formula:

Finally, to find the 9th therm in our sequence, we just need to replace

with 9 in our explicit formula:



We can conclude that the 9th term in our geometric sequence is <span>

Answer:
<u>Gina's height in inches</u><u>:</u> 63 inches
<u>Noelle's height in inches</u><u>:</u> 67 inches
<u>Equation</u><u>:</u> n + (n - 4) = 130
Step-by-step explanation:
n + (n - 4) = 130
n + n - 4 = 130
2n - 4 = 130
2n - 4 + 4 = 130 + 4
2n = 134
2n ÷ 2 = 134 ÷ 2
n = 67
67 - 4 = 63
