Answer:
x^2−
2
+
1
5
Step-by-step explanation:
First we need to find the common ratio by dividing the second term by the first term. 36/120 = 3/10
an = a1 * r^(n-1)
n = term to find = 5
a1 = first term = 120
r = common ratio = 3/10
now we sub and solve
a5 = 120 * 3/10^(5 - 1)
a5 = 120 * 3/10^4
a5 = 120 * .0081
a5 = 0.972 <=== fifth term
or we could have just done this......since we multiply by 3/10 to find the next number...
a3 = 10.8......10.8 * 3/10 = 3.24 <== 4th term
3.24 * 3/10 = 0.972 <== fifth term
So we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length
Answer:

Step-by-step explanation:
Sarah's number: 13285
The digit '3' in Sarah's number worth = 3000
The digit '3' in Caryn's number is worth 10 times the digit '3' in Sarah's number: it's worth 10 × 1000 = 10000
Caryn wrote 5 digit number, and this number only have one digit '3'
Caryn's number could be:
35642
321547
30789
