Answer:
 Not going to give answer, but let you solve
Step-by-step explanation:
You first have to start by drawing a number line and mark two integers between the fraction lines. Then you have to divide the section between the two integers in an equal number of parts which is equal to the denominator.

81 a² - 25  is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)
 is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)
Step-by-step explanation:
The difference of two squares is a binomial of two terms each term is a square and the sign between the two terms is (-), its factorization is the product of two identical binomials with different middle signs
- a² - b² is a difference of two squares
- a² - b² = (a + b)(a - b)
∵ The binomial is 81 a² - 25  
 
∵  = 9
 = 9
∵  = a
 = a
∴ 
∵  = 5
 = 5
∵  = z³
 = z³
∴ 
- The two terms have square root
∵ The sign between them is (-)
∴ 81 a² - 25  is a difference of two squares
  is a difference of two squares
∵ Its factorization is two identical brackets with different 
    middle signs
∵ 81 a² = 9a × 9a
∵ 25  = 5z³ × 5z³
 = 5z³ × 5z³
- The terms of the two brackets are 9a and 5z³
∴ 81 a² - 25  = (9a + 5z³)(9a - 5z³)
 = (9a + 5z³)(9a - 5z³)
81 a² - 25  is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)
 is a difference of two squares and its factors are (9a + 5z³) and (9a - 5z³)

Answer: 2/5
Step-by-step explanation:
Number of cans of red paint = 3
Number of cans of blue paint = 5
Number of cans of green paint = 8
Number of cans of yellow paint = 4
Total number of cans of paint = 20
The probability that Eduardo will
choose a can of red paint or a can of blue will be:
= P(red) + P(blue)
= 3/20 + 5/20
= 8/20
= 2/5
The probability is 2/5.
