Answer:

x³ + 5x² + 5x - 2

Step-by-step explanation:

Combine like terms.

x³ + 3x² − x + 2x² + 6x − 2 =

= x³ + 5x² + 5x - 2

The volume of the box when it's filled to 3 inches deep is 12×8×3 = 288 in³

The box is filled up to 1.5 inches from the top, that means the box is filled only
3-1.5 = 1.5 inches deep

The volume of the box when it's filled to 1.5 inches deep is 12×8×1.5 = 144 in³

The number of flours saved is 288 - 144 = 144 in³

Which of the following lines is perpendicular to the x-axis and contains the point (-11.4, 12.8)
sergejj [24]

The line x = -11.4 is perpendicular to the x-axis and contains point

(-11.4 , 12.8)

Step-by-step explanation:

Let us revise the equations of the vertical lines and horizontal lines

  • The vertical line is a line parallel to y-axis
  • The x-coordinates of all points lie on the line are equal
  • The equation of the vertical line basses through point (a , b) is x = a
  • The horizontal line is a line parallel to x-axis
  • The y-coordinates of all points lie on the line are equal
  • The equation of the horizontal line passes through point (a , b) is y = b
  • The vertical line and the horizontal line are perpendicular to each other when intersect each other

∵ The line is perpendicular to the x-axis

∴ The line is a vertical line

∴ The equation of the line is x = a, where a is the x-coordinate

   of any point lies on the line

∵ The line contains point (-11.4 , 12.8)

∵ The x-coordinate of the point is -11.4

∴ a = -11.4

∴ The equation of the line is x = -11.4

The line x = -11.4 is perpendicular to the x-axis and contains point

(-11.4 , 12.8)
