The lenght of the square-shaped field edge is 240 meters. Calculatr the field area in hectares

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28

If f(x) = 3x-2 and g(x) =2x+1 find (f-g)(x)

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
