Answer:

-30

Step-by-step explanation:

Plug in the values of x and y: 6 - 3(12)
3(12) = 3 × 12 = 36
Plug 36 in: 6 - 36
6 - 36 = -30

I hope this helps!

What is the area of the shaded region and the circle inside?

$r=20,1m+13,2m=33,3m$
$A_1=\pi r^2$
$A_1=33,3^2\pi$
$A_1=1108,89\pi$

What is the area of the circle inside?

$A_2=20,1^2\pi$
$A_2=404,01\pi$

What is the area of the shaded region?

$1108,89\pi -404,01\pi =704,88\pi$
$704,88\pi \approx 704,88*3,14\approx 2213,3232\approx \underline{2213,32}$

The answer: 2213,32 :)

Answer:

d. x = -3

Step-by-step explanation:

<u /> $\sqrt{(x + 3)}$ ÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u /> $\sqrt{(x + 3)}$ = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3
