Answer:
The equation is 
..
The length of the towel bar is 
..
Step-by-step explanation:
Given,
Length of the door = 
we can rewrite as 
.
We have to find out the length of the towel bar.
Let the length of towel bar be 'x'
`Since Vita wants that the distance from each end of the towel bar to the end of the door to be 9 inches.
So we can say that the length of the towel bar plus from each end of the towel bar to the end of the door plus from each end of the towel bar to the end of the door is equal to length of door.
framing in equation form, we get;
Hence The equation is .
Now we solve the equation we get;
Subtracting both side by 18 we get;
Now we will make the denominator common we get;
Hence The length of the towel bar is .
(4b+3) (2b−5)
(4b+3) (2b+−5)
(4b) (2b) + (4b) (−5) +(3) (2b) +(3) (−5)
8b²−20b+6b−15.
= 8b²−14b−15.
The number of videos will be 3 and the number of CDs will be 2.
<h3>What is an expression?</h3>
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Christine went shopping and bought each of her five nephews a gift, either a video costing $14.95 or a CD costing $16.88. She spent $78.61 on the gifts.
The number of the videos and CD will be calculated by forming an equation:-
14.95x + 16.88y = 78.61
From heat and trial, we put x = 3 and y = 2 then calculate.
14.95 x ( 3 ) + 16.88 x ( 2 ) = 78.61
44.85 + 33.76 = 78.61
78.61 = 78.61
Therefore, the number of videos will be 3 and the number of CDs will be 2.
