Find the perimeter and area of a square with a side of 7 feet.

the perimeter of a square = 28 feet.

the area of a square = 49 ft²

Step-by-step explanation:

given:

side length of a square = 7 feet.

find:

perimeter (P) of a square

area (A) of a square

Perimeter of a square = 4s

P = 4(7)

P = 28 feet.

area of a square = s²

A = 7²

A = 49 ft²

therefore,

the perimeter of a square = 28 feet.

the area of a square = 49 ft²

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
