Write the equation of a circle with a center at (12, 6) and a radius of 6.

uranmaximum [27]

Answer:

(x-12)² + (y-6)² = 36 (Option C)

Step-by-step explanation:

use circle formula

(x-h)² + (y-k)²= r²

h= 12 and k= 6 and r= 6

(x-12)² + (y-6)² = 6²

6 squared = 36 (6·6)

(x-12)² + (y-6)² = 36

Factor the expression completely.

densk [106]

Answer:

$\fbox{\begin{minipage}{13em}Option D: 2(3x + 4)(3x - 4)\end{minipage}}$

Step-by-step explanation:

$A = 18x^{2} - 32\\$

Find the sharing components:

<=> $A=2*9*x^{2} - 2*16$

Apply the inverse of associative property:

<=> $A = 2(9x^{2} - 16)$

Identify two square components inside the parenthesis:

<=> $A = 2((3x)^{2} - 4^{2} )$

Factorize:

<=> $A = 2(3x + 4)(3x - 4)$

=> Option D is correct

Hope this helps!
