Answer:
center = (-2, 6)
radius = 6
Step-by-step explanation:
<u>Equation of a circle</u>
(where (a, b) is the center and r is the radius)
Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.
Given equation:
Collect like terms and subtract 4 from both sides:
Complete the square for both variables by adding the square of half of the coefficient of 
and 
to both sides:
Factor both variables:
Therefore:
- center = (-2, 6)
- radius = √36 = 6
Answer:
square root 29
Step-by-step explanation:
use the distance formula sqrt(x2-x1)^2+(y2-y1)^2
sqrt(-1-4)^2+(3-5)^2= sqrt 29.

Answer:
53
Step-by-step explanation:
they are a linear pair so x + 2x + 21 = 180 so you subtract 21 from both sides, combine x and 2x then divide by 3 to get 53
<u> 1 liter </u> = <u>12 km
</u>3 liters x km
<u>
</u>x= 12km x 3 liters ÷ 1 liter
<u />x= 36 km
But since we want to know how many METERS the car can travel, convert km to m:
<u> 1 km </u>= <u>1000m</u>
36 km y m
y= 1000 x 36m ÷ 1 km
y= 36000m
Hope this helps!
