Answer:
C = 12.56m
Step-by-step explanation:
circumference is the distance around the outside of a circle. The r stands for radius, half way across, from the center(thats the little line on the diagram) "d" stands for diameter. That would be double the radius, bc its all the way across the circle through the center. The formula to find the CIRCUMFERENCE is given, C=pi × d
They told you to use 3.14 for pi. And also the radius is 2, so the diameter is 4
C = pi × d
C = 3.14 × 4
C = 12.56 meters
Your answer is c, an obtuse triangle because if the two side lengths are the same length along with a longer side, it become obtuse

Answer:
C
Step-by-step explanation:
Factor: -7x^2 -5x+18
Factor -1 out of 7x^2 -5x +18:
−(7x^2+5x−18)
Factor.
1. 18 is negative, so a negative number multiplied by a postive number.
2. You can't factor 7, so 7x times x.
(7x−9)(x+2)
