Answer:
B is -6.
Step-by-step explanation:
y=mx+b
6 is negative and is in the place of the y intercept (b)

Answer: 6π
Step-by-step explanation:
Area of a circle = πr².
To find the circumference, we have to find the radius first
Since the area of the circle in question is 9πcm²
9π = πr²
r² = 9π/π
r² = 9
r = +/-√9
= +/- 3.
To find the circumference now, we substitute for r in the formula above
Circumference = 2πr
= 2 x π x 3
= 6π.
Don't forget the π there must not be define
So the answer = 6π
Answer:
Obtuse scalene triangle
Step-by-step explanation:
1. Angles:
- -> Acute triangle: all angles less than 60°
- -> Right triangle: one angle is 90°
- -> Obtuse triangle: one angle is greater than 90°
- Given the information above, we can see that the triangle has one angle that's greater than 90° (129°), so this triangle is obtuse.
2. Sides:
- -> Scalene triangle: all sides have different lengths
- -> Isosceles triangle: two sides have same length
- -> Equilateral triangle: all sides are the same
- Given the information above, we can see that all the sides in the triangle are different, so this triangle is scalene.
Therefore, the answer is an obtuse scalene triangle.
That question is hard try google that always helps me
