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:

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

Answer:

$\frac{10}{9}\pi$ yards

Step-by-step explanation:

The circumference of this circle = 2πr

= 8π

We have to find the arc length of 50°, or 50/360 times the circumference of the circle(because there is 360° in a circle)

$\frac{50}{360} * 8\pi = \\\\\frac{400\pi}{360} =\\\\ \frac{10\pi}{9}$

Answer:

We can use the distributive property.

(x + 2)(y - 1)

= x(y) - x(1) + 2(y) - 2(1)

= xy - x + 2y - 2

=3(18×8)

=3(144)

$432 {cm}^{2}$

Total Surface area

$80 {cm}^{2} + 432 {cm}^{2} \\ 512 {cm}^{2}$
