Give me the answer pls!

Square Area = ( one side length)²

784 = (AB)²

AB = 28

circle radius = 14

pi = 3.142

semi circle parameter = pi × r

= 3.142 × 14 = 43.988

square parameter = 3 × 28 = 84

we dont calculate the 4th side.

parameter of the figure = 43.988+ 84= 127.988

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

step-by-step explanation:

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
