Answer:
80 units
Step-by-step explanation:
The star has 10 sides. If each side is 8 units, then the perimeter is 10(80) because the perimeter is the sum of the lengths. With each length being 8, you could add 8 to itself 10 times, but it is faster to multiply.
Coordinates of the center: ( 4, 4 )
The radius: r = 7 - 4 = 3
The equation of a circle:
( x - 4 )² + ( y - 4 )² = 3²
x² - 8 x + 16 + y² - 8 y + 16 = 9
x² + y² - 8 x - 8 y + 32 - 9 = 0
Answer:
A ) x² + y² - 8 x - 8 y + 23 = 0
Because any number times itself is the number
Step-by-step explanation:
51 is not a prime number because it is divisible by 1,3 and 17
and we know prime number are only those number who arenot divisible by any other number except 1
