Answer:

f(-2) + 9 is 19

Step-by-step explanation:

$f(x) = - 3x - 2$

when x is -9:

$f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10$

sum up with 9, f(-2)+9:

$f( - 2) + 9 = 10 + 9 \\ = 19$

The volume of the regular pyramid is $V=\dfrac{1}{3}A_{base}H.$

The base of given pyramid is regular hexagon with side 12 cm. The are of this hexagon consistsof area of 6 equilateral triangles and is equal to

$A_{base}=6\cdot \dfrac{1}{2}\cdot 12\cdot 10.4=374.4\ cm^2.$

Hence, the volume of the pyramid is

$V=\dfrac{1}{3}\cdot 374.4\cdot 36=4,492.8\ cm^3.$
