The answer is 3 because you have to do inverse operation on inequalities.
The diameter is the line that goes through the middle of a circle and the radius goes from the center to a point in the circle so r = d/2 or d =2r
C. d/2
Answer:
w=12 or w=2
Step-by-step explanation:
2w^2-16w=12w-48
2w^2-28w=-48
2w^2-28w+48=0
2(w^2-14w+24)=0
2(w-12)(w-2)=0
(w-12)(w-2)=0
w=12 or w=2
Triangles have 3 vertices. The total is 21 vertices. 21 / 3 = 7. He drew 7 triangles.
