Answer: option b

Step by step explanation; surface area is the value that expresses the amount of area you can touch on a figure

Since there's four triangular faces, you do 4*(1/2*8*15)

Since there's one square face, you do (8*8)

Together, you expression is (8 * 8) + 4 *(1/2 * 8 * 15)

Which is 394

Answer:

x < -3

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

$4x + 6 - 6 < -6 - 6$
$4x < -12$

Step 2: Divide both sides by 4.

$\frac{4x}{4} < \frac{-12}{4}$
$x < -3$

Therefore, the answer is x < -3.
