Hello there! I can help you! The absolute value symbols make the answer to the expression between the lines positive. Because of this, let's solve as two separate equations: k + 7 = 3, and k + 7 = -3. Let's start with the first one. 3 - 7 is -4. k = -4. Now to the second one. -3 - 7 is -10. Keep in mind that -10 works, because although the sum is -10 and 7 is -3, the sum has an absolute value of 3. There. k = -10 or - 4. The answer is D.
Answer:
![c = 9](https://tex.z-dn.net/?f=c%20%3D%209)
Step-by-step explanation:
![{(x - a)}^{2} = {x}^{2} - 2ax + {a}^{2} \\ 2ax = 6 \\ a = 3 \\ c = {a }^{2} \\ c = 9](https://tex.z-dn.net/?f=%20%7B%28x%20-%20a%29%7D%5E%7B2%7D%20%20%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%202ax%20%2B%20%20%7Ba%7D%5E%7B2%7D%20%20%5C%5C%202ax%20%3D%206%20%20%5C%5C%20a%20%3D%203%20%5C%5C%20c%20%3D%20%20%7Ba%20%7D%5E%7B2%7D%20%20%5C%5C%20c%20%3D%209)
