Area = length times width

A = (3x^2 - 4x + 6)(x - 6)

A = 3x^3 - 4x^2 + 6x - 18x^2 + 24x - 36

A = 3x^3 - 22x^2+ 30x - 36

Done!

At least they admitted this is algebra not geometry. You'll get the same question next year but they'll call it geometry.

The area is the product of the sides:

A=(x-6)(3x^2-4x+6)

We just distribute and collect terms:

A=x(3x^2-4x+6) - 6(3x^2-4x+6)

A=3x^3-4x^2+6x - 18x^2 +24x -36

A=3x^3- 22x^2+30x-36

Answer: 3rd choice

prisoha [69]

Answer:

The distance between the two train stations is 1728 km

Step-by-step explanation:

The speed of the bus = 54 km/h

The speed of the truck = 48 km/h

When the bus and truck meet again, the distance covered by the bus = 216 km more than he distance traveled by the truck

Let the distance between the two train stations = x

Let the location where they first meet be y from station A we have;

The location where they meet again = y - 216 km

Therefore, we have;

Location where they

The time for the truck and the bus to meet again = t

Therefore, 54 × t - 48 × t = 216 km

6·t = 216 km

t = 36 hours

Therefore, the time for the bus to travel x + 216 km = 36 hours

54 × 36 = 1944 = x + 216

x = 1944 - 216 = 1728 km

The distance between the two train stations = 1728 km.

The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown.
omeli [17]

Answer:

The area of one trapezoidal face of the figure is 2 square inches

Step-by-step explanation:

<u><em>The complete question is</em></u>

The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown. What is the area of one trapezoidal face of the figure?

we know that

The area of a trapezoid is given by the formula

A=\frac{1}{2}(b_1+b_2)h

where

b_1 and b-2 are the parallel sides

h is the height of the trapezoid (perpendicular distance between the parallel sides)

we have

h=1\ in\\b_1=1\ in\\b_2=3\ in

substitute the given values in the formula

A=\frac{1}{2}(1+3)(1)

A=2\ in^2
