On a piece of paper, graph y<_3x. Then determine what answer matches the graph you drew. Help plz

Step-by-step explanation:

Draw the solid line y = 3x.  Now shade the region below this line.

I will simply invent a point:  (2, -1).  Here y = -1 and x = 2.  Either this point is in the shaded region or it is not.  Substituting 2 for x in y  ≤ 3x, we get

y ≤ 3(2), or y ≤ 6.  Is -1 less than 6?  YES.  So the (arbitrarily chosen) point (2, -1) is a solution of the given inequality.

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

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
