Answer:
x = ± 4
Step-by-step explanation:
given 3x² = 48 ( divide both sides by 3 )
x² = 16 ( take the square root of both sides )
x = ±
= ± 4
x ∈ {- 4, 4 }
Please rewrite this equation of the circle correct with signs of minus or plus
Answer:

Step-by-step explanation:
The general equation for a circle is

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
Divide the number of bands by the total acts:
3 /16 = 0.1875
Multiply by 100:
0.1875 x 100 = 18.75% were bands. ( Round answer as needed.)
