Rectangle, triangle, and I believe square
Answer:
Brenda ran 263.76 metres.
Step-by-step explanation:
The circumference of a circle is two times pi times its radius. Brenda rand that twice, so we need:
2 × 2πr
= 4πr
= 4 × 3.14 × 21m
= 263.73m
After cleaning up the algebra to transform this equation into y=mx+b form you should get y=-1x+5.
Slope is -1
It’s should be $0.14 if I did the math correctly
