Answer: 84 ft^2

Step-by-step explanation:

The whole prism can be divided into 5 surfaces.

Two triangles and 3 rectangles.

Find the area of each of the 5 shapes and add them together.

The triangle has a base of 4 and a height of 3.

Area of triangle 1: A= 4*3 * 1/2

A = 6

Area of triangle 2: A = 4*3 * 1/2

A = 6

Area of rectangle 1 : A= 4*6

A = 24

Area of rectangle 2; A = 3*6

A = 18

Area of rectangle 3: A= 5 *6

A = 30

Now add the areas together

6 + 6 + 24 + 18 + 30 + = 84 ft^2

Answer:

$e(2x^{2} -12x)-4x^{2}+C$

Step-by-step explanation:

We have been given an indefinite integral as $\int \left(4x-12\right)e-8x\:dx$ . We are asked to find the given integral.

Let us solve our given problem.

$\int \left(4x-12\right)e\:dx-\int 8x\:dx$

Take out constant:

$e\int \left(4x-12\right)\:dx-8\int x\:dx$

$e(\int 4x\:dx -\int 12\right\:dx)-8\int x\:dx$

$e(\frac{4x^{1+1}}{2} -12x)-8*\frac{x^{1+1}}{1+1}+C$

$e(\frac{4x^{2}}{2} -12x)-8*\frac{x^{2}}{2}+C$

$e(2x^{2} -12x)-4x^{2}+C$

Therefore, our required integral would be $e(2x^{2} -12x)-4x^{2}+C$ .
