The equation of a circle:
(h, k) - a center
r - a radius
We have:
The center (-3, -4) → h = -3 and k = -4.
The radius is equal the distance between the center of the circle and the origin.
The formula of a distance between two points:
Substitute
therefore r = 5.
Answer:
Answer:
4.2
Step-by-step explanation:
10% of 42 is 4.2
Answer:
14 inches
Step-by-step explanation:
Using this information, we can form an equation.
Since there are 3 sides in a triangle, and each side increased by 6, that means that the perimeter increased by 18 inches. Down below, I did 3x because there are 3 sides in a triangle.
(This is the equation you'd want to do to get the answer)
3x + 3 * 6 = 60
Simplify:
3x + 18 = 60
Same to both sides
3x = 42
Isolate x:
x = 14
Let me know if you have any questions
6 times 30 x 6= 180 So the answer is 6
449.55 x .333 = 149.70 if rounded from 149.70015
449.55 - 149.70 = 299.85
