Answer:
The simplified expression is
20x^2 - 33x - 27
Step-by-step explanation:
(6x - 9 - 2x)(8 + 5x - 5)
We must first rewrite the expression as a product of two binomials.
This can be done by adding like terms
(6x - 9 - 2x)(8 + 5x - 5)
We have,
(4x-9)(5x+3)
Multiplying the resulting binomial expression
(4x-9)(5x+3)
(20x^2+12x-45x-27)
Add the like terms
20x^2-33x-27
The simplified expression is
20x^2 - 33x - 27
Twenty x squared minus thirty-three x minus twenty-seven

(A) The formula for nth bounce is 
.
(B) 4.43 feet is the maximum height of the ball on the 6th bounce.
<h3>What is an algebraic expression?</h3>
An algebraic expression is consists of variables, numbers with various mathematical operations,
Given that,
The height from where the ball is dropped = 20 feet.
Also, the ball bounces and returns to 7/9 to its original height.
(A)
The representation of the maximum height of the ball on the nth bounce can be given as
(B)
The maximum height of the ball on the 6th bounce = 20 (7/9)⁶ = 4.43 feet

Answer: 7/75
Step-by-step explanation: An event may either be dependent or independent, depending on the effect the outcome of such event has on other events. A dependent events is one in which it's out ime is affected by the outcome of another event. On the other hand an independent event is not affected by the outcome of another event.
The event described above is a dependent event, because the outcome of my first try or pick will affect the possible outcome of my friend's first try.
Candy dish :
5 butterscotch ; 8 peppermint ; 12 chocolate
I and my friend both want peppermint:
P = required outcome ÷ Total possible outcome
Total possible outcome = 5+8+12 = 25
P(I pick peppermint on my first try) = 8/25
P(my friend picks peppermint on her first try) = 7/24
If I pick first, the outcome of my friend's event has been affected from the original
P = (8/25) × (7/24)
P = 56/600
P = 7/75
