Answer:IS B OR D BUT I SAY D
Step-by-step explanation:
Try this solution:1. to make up the characteristic equation:α²+5α=0;

2. to make up the final answer:y=C₁+C₂e⁻⁵ˣ
So 55% is really 55/100
You take 100 - 55 to find how much Mr. Williams drove
100 - 55 = 45
So Mr. Williams drove 45/100 of the miles
Simplified is 9/20 of the miles
The surface are would be 81 bc the base area is 9 and you have four triangles with the area of 18. Add them all up and you get 81
