Answer:
k = 10
Step-by-step explanation:
The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.
So 10k + 15 must equal the remaining 115
subtract 15 from each side and you get 10k = 100
divide each each by 10 and you get the answer of k = 10
Answer:
A. 2x+21
Step-by-step explanation:
distribute 3 through the parentheses then it gives you 6x-6x+21+2x so do 6x-6x=0 giving you 21+2x or 2x+21
Answer:
Step-by-step explanation:
6(5+13x)-13(1-x)
30+78x-13+13x
30-13+78x+13x
17+91x

Answer:</h3>
1) Radius: 2√7
2) Center: (10, 5)
3) Circumference: 33.25
<h3>
Explanation:</h3>
Circle formulae:
where (h, k) is the center coordinates, r is radius
Rewrite the equation into standard form:
- (x-(10))² + (x - (5))² = (√28)²
Identify following of the circle:
- h = 10, k = 5, radius = √28 = 2√7
In order to find the Circumference of circle:
- Use the formula: 2π(radius)
radius: 2√7
- Circumference: 2π(2√7) = (4√7)π = 33.2475 = 33.25
[(x**-2) y**2 .z)**2]**2 (x**-8)(y**8)(z**4)
----------------------- = -----------------------------
[x**2 . y**3]**2 (x**4) (y**6)
(y**8)(z**4) (y**2)*(z**4)
