Step-by-step explanation:
Given number
It is not in scientific notation because:
- <em>The proper format for scientific notation is a×10ᵇ where </em><em>a</em><em> is a number or decimal number such that </em><em>the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10</em>

Answer:
24 Tennis balls
Step-by-step explanation:
Calculation for How many tennis balls are left
First step
Since we have 12 can with 3 balls each Let the number of balls that the tennis pro has at the beginning be x
x=(12 can ×3 balls each)
x=36
Second step
Since we have 4 players who lost 3 ball each Let the total number of balls that was lost be y
y=(4 players×3 balls each)
y=12
Third step is to calculate How many tennis balls are left
Since x represent the number of balls at the beginning and y represent the number of balls that was lost , then let the number of tennis balls that was left after the session represent z
z=36−12
z=24 Tennis balls
Therefore the numbers of tennis balls that are left will be 24 Tennis balls
Answer:
Step-by-step explanation:
our lengths are:
7.5a-1.5b, 3.5a+4.5b, 6.5c+2a, 8.5-6.5c
P=7.5a+3.5a+2a-1.5b+4.5b+6.5c-6.5c+8.5=16a+3b+8.5
