Answer:
x = -25/12 or x = -0.2
Step-by-step explanation:
x(x+5)+6(x+5)=(x+5)
Distribute
x^2 + 5x + 6x + 30 = x + 5
Combine
x^2 + 11x + 30 = x + 5
Subtract 1x from both sides
x^2 + 10x + 30 = 5
Subtract 30 from both sides
12x = -25
Divide 12 on both sides
x = -25/12 or -0.2

Actual cost of the TV = $175.95
Percentage of discount given on the TV = 20%
Then
Amount of discount on the TV = (20/100) * 175.95 dollars
= 175.95/5 dollars
= 35.19 dollars
So cost of the TV after discount = (175.95 - 35.19) dollars
= 140.76 dollars
Now
Percentage of sales tax that needs to be added = 6%
Then
Amount of sales tax that needs to be added = (6/100) * 140.76 dollars
= 844.56/100 dollars
= 8.45 dollars
Then
Price of TV after adding sales tax = (140.76 + 8.45) dollars
= 149.21 dollars
So the cost of the TV after deducting the discount and adding the sales tax is $149.21
