Solve the following system

y=1.6x
2x + 2y = 86

The answer is (16.538461(repeated), 26.461538(repeated))

x=16.538462 and y=26.461538

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

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
