(x + 2)(3x – 1) = 0

X^2+4x=0

2m^2-128=0

2x^2+3x-14=0

Step-by-step explanation:

x^2+4x=0

therefore x=-4

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
