a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. what is the surface area of the pri

laiz [17]

For this case we have that the surface area of the prism is given by:

$SA = A_ {l} + 2B$

Where:

$A_{l}$ : Is the lateral area

B: It is the area of the base

$A_ {l} = P.h$

Where:

Q: It is the perimeter of the base

h: It's the height

$A_ {l} = 40 * 4\\A_ {l} = 160 \ in ^ 2$

On the other hand:

$B = 12 * 8\\B = 96 \ in ^ 2$

So, we have:

$SA = A_ {l} + 2B\\SA = 160 \ in ^ 2 + 2 * 96 \ in ^ 2\\SA = 352 \ in ^ 2$

Answer:

$SA = 352 \ in ^ 2$

Evaluate the function f(x) = 2x3 - 6x + 1 for f(-2).

erma4kov [3.2K]

Answer:

- 3

Step-by-step explanation:

$f(x) = 2 {x}^{3} - 6x + 1 \\ plugging \: x = - 2 \\ f( - 2) = 2( { - 2})^{3} - 6( - 2)+ 1 \\ = 2 \times ( - 8) + 12 + 1 \\ = - 16 + 13 \\ = - 3 \\ f( - 2) = - 3$
