Answer:

SA = 108 ft^2

Step-by-step explanation:

The front and back faces are triangles with 4 ft base and 3 ft height.

The three sides are rectangles with dimensions 4 ft by 8 ft, 8 ft by 5 ft, and 3 ft by 8 ft.

The surface area is the sum of the areas of the two triangles and the three rectangles.

SA = 2 * (1/2)(4 ft * 3 ft) + 4 ft * 8 ft + 8 ft * 5 ft + 3 ft * 8 ft

SA = 12 ft^2 + 32 ft^2 + 40 ft^2 + 24 ft^2

SA = 108 ft^2

Answer:

x ≈ 2.87

Step-by-step explanation:

We can subtract 6 to put the equation into a form easily solved.

x^2 +2x +1 = 15

(x +1)^2 = 15

x +1 = √15 . . . . . for the greatest solution, we only need the positive root

x = √15 -1 ≈ 2.87
