Answer:

A) 2a + 6

Step-by-step explanation:

(5a + 3) + (2a + 3) + x = 9a + 12

Add both side lengths plus the unknown side to equal the perimeter.

7a + 6 + x = 9a + 12

-7a -6 -7a -6 Subtract 7a + 6 on both sides

x = 2a + 6 This is the missing side length.

Talja [164]

Answer:

<u>x² - 22x + y² - 6y + 121 = 0</u>

Step-by-step explanation:

<u>General Form of Equation</u>

(x - h)² + (y - k)² = r²

<u>Solving</u>

(x - 11)² + (y - 3)² = (3)²
x² - 22x + 121 + y² - 6y + 9 = 9
<u>x² - 22x + y² - 6y + 121 = 0</u>
