Answer:

<h3>The answer is option B</h3>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

l = 12m

w = 400 cm

First we must convert the length from meters to centimeters

1 m = 100 cm

12 m = 12 × 100 = 1200 cm

So l = 1200 cm

Substitute the values into the above formula

We have

Perimeter = 2(1200) + 2(400)

= 2400 + 800

We have the final answer as

<h3>Perimeter = 3200 cm</h3>

Hope this helps you

The GCF is the largest number that can go into both the terms. Since "y" isn't in both terms, it can't include y. x, however, is, so we know our GCF has x in it. What's the largest whole number that can go into 32 and 18? 2. Your GCF is <span>2x.

F(n) = 2• (-3)^n
Mashutka [201]

Answer:

f(1)=-6

f(n)=f(n-1)(-3)

Step-by-step explanation:

We are given that

f(n)=2\cdot (-3)^n

We have to complete  the recursive formula of f(n).

Substitute n=1

f(1)=2\cdot (-3)

f(1)=-6

f(2)=2\cdot (-3)^2=18

f(3)=2\cdot (-3)^3=-54

\frac{f(2)}{f(1)}=\frac{18}{-6}=-3

\frac{f(3)}{f(2)}=\frac{-54}{18}=-3

It forms geometric sequence because the ratio of two consecutive terms are equal.

Therefore, the recursive formula

f(n)=f(n-1)r

f(n)=f(n-1)(-3)
