The common ratio of both the formulas is 3 and 2. The first formula is explicit and the second is the recursive formula.
<h3>What is the recursive rule?</h3>
A rule is defined such that its definition includes itself.
1.
The given sequence is
-2, -6, -18, -54
Common ratio ;
r = -6 / -2 = 3
This given formula is the explicit formula.
2.
The given sequence is
4, 8, 16, 32
Common ratio ;
r = 8 / 4 = 2
This given formula is the recursive formula.

10^2+15^2=
100+225=325
The square root of 325 is 18.0277563773 is you round it to the hundredths place it’s 18.03
This is saying, when x is 6, what is the value of you. f(x) is y
y=3(6)-5
y=18-5
y=13
Answer is 13

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any diagram so I'll assume we are talking about a square. If so, then the area of the square is given by:
From the figure below, we know that the side of the square is:
So the area can be found as:
Finally:
<em>The shaded region has an area of 40 square meters</em>
Answer:
A. -2x^2-2x-2
Step-by-step explanation:
(2x^2-5x-4)-(4x^2-3x-2)
distribute the minus sign
(2x^2-5x-4)-4x^2+3x+2
2x^2-5x-4
-4x^2+3x+2
-------------------------
-2x^2 -2x-2
