Answer:
Step-by-step explanation:
To find the nth term of a geometric sequence, you have the general formula:
where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):
135 =
135 =
135 =
Now, we can substitute the first term back in:
Answer:
width = 5 in
length = 5+4=9 in
height = 2(5)= 10 in
Step-by-step explanation:
A gift box has a volume of 450 cubic inches.
Let 'w' be the width of the box
The width of the box is 4 inches less than the length.
The height is twice the width.
height = 2w
Volume of box = length times width times height
w=5
, this gives two complex values
so width = 5
length = 5+4=9
height = 2(5)= 10
