1. descending order (greatest to least): 7a3+5a2b-4b-13ab
2. classification: 4 terms
3. the degree: 3
Multiply the ratio by $5.35
racket : balls = 18×$5.35 : 1×$5.35 = $96.30 : $5.35
The racket costs $96.30.
Answer:
20 + 2 units
Step-by-step explanation:
because the perimeter of ∆ ABC is the answer 20 + 2
Circumference=2pi*r
20.7=2pi*r
r=3.296 or 3.3
A=pir^2
a=34.1946 or about 34.19
