Answer:

arithmetic series

Step-by-step explanation:

We are adding 1 each time , so this is an arithmetic sequence

a1 =5

The common difference is 1 so d=1

an = a1+d(n-1)

an = 5 + 1(n-1)

an = 5+n-1

an = n+4

If we have an arithmetic sequence, we have an arithmetic series when we add the arithmetic sequence

The perimeter of the square kitchen floor measures 48 feet. What is the area of the kitchen floor? A. 32 feet B. 96 square feet

exis [7]

Answer:

C. 144 square feet

Step-by-step explanation:

step 1

we know that

The perimeter of a square is given by the formula

$P=4a$

where

P is the perimeter

a is the length side of the square

we have

$p=48\ ft$

substitute in the formula

$48=4a$

solve for a

divide both sides by 4

$a=12\ ft$

step 2

Find the area

The area of a square is given by the formula

$A=a^2$

we have

$a=12\ ft$

substitute

$A=12^2=144\ ft^2$
