You would want to do the square root of 361 which is 19
Hope This Helps!
ps. no, I'm not stalking u I just clicked on the next question from your last one.
Step-by-step explanation:
2x-y=8
x+y=20
------------
3x=28
×=28÷3=9.3
so
9.3+y=20
y=20-9.3
y=20.7
Answer:
Let's complete the square first.
y = x² + 6x + 3
= (x² + 6x + 9) - 6
= (x + 3)² - 6
Therefore, the vertex is (-3, -6) and since the coefficient of (x + 3)² is positive, the vertex is a minimum.
The answer is 7, because you multiply it by 6.
X intercept: (-4)
y intercept: (8)
