Answer:

x² +y² = 16

Step-by-step explanation:

The diagonal of a square is √2 times the side length, so the diameter of a circumscribed circle is √2 times the diameter of an inscribed circle. Each of the two outer circles is √2 times the diameter of the one just inside it, so the outer circle is (√2)(√2) = 2 times the diameter of the inner circle.

The equation of the largest circle with radius 2·2=4 is ...

x² +y² = 16

NISA [10]

Answer:

Your Answer is ...

x > 3 or x < -7

Step-by-step explanation:

1. x > 3 worked out

|X + 2| > 5

Solve absolute Value

|X + 2| > 5

We know either |X + 2| > 5 or x + 2 < - 5

_________________________________

$x + 2 > 5\\x + 2 - 2 > 5 - 2 (Subtract ~2~ from~Both~sides)\\ x >3$

2. x < -7 Worked out

$x + 2 < - 5\\x+2-2>5-2 (Subtract~2~from~Both~sides)\\x$

Hope this Helps!
