Answer:

Step-by-step explanation:
We have to find the formula for the value of 'l'.
So, we will isolate 'l' on one side of the formula.
A = 2lw + 2lh + 2wh
A = 2l(w + h) + 2wh
A - 2wh = 2l(w + h) + 2wh - 2wh
A - 2wh = 2l(w + h)


Therefore, formula for 'l' will be,

Answer: 55
Step-by-step explanation:
Let the number of cars washed last year be denoted as x.
This year, he washed 14 fewer cars than during last year's car wash. This will be denoted as x-14.
We can then represent them in an equation as:
x + (x - 14) = 96
2x - 14 = 96
2x = 96 + 14
2x = 110
x = 110/2
x = 55
Therefore, he washed 55 cars this year

Im not sure tho but should be fine
Answer:
23 child tickets were sold
Step-by-step explanation:
Using the information given, we can set up an equation to solve for the number of child tickets sold. Since there were three times as many adult tickets as child tickets sold, we can assign the variable 'x' to represent the number of child tickets and '3x' to represent the number of adult tickets. Since we know the cost of each ticket, as well as the total sales, we can set up the following equation:
5.20x + 9.70(3x) = 788.90
Simplify 5.20x + 29.1x = 788.90
Combine like terms: 34.3x = 788.90
Divide both sides by 34.3: x = 23 child tickets
