The equivalent expression to Daryl's expression is -5 + 7d ⇒ d
Step-by-step explanation:
In a regular polygon of n-side
- All sides are equal in lengths
- All angles are equal in measures
- Its perimeter is n × the length of one side
∵ The polygon is a pentagon
∴ n = 5
∵ The pentagon is regular
∴ The lengths of its 5 sides are equal
∵ Its perimeter = 5 × length of one side
∵ Its perimeter = 35d - 25
- Equate the two sides of the perimeter
∴ 5 × length of one side = 35d - 25
- Divide both sides by 5
∵ 35d ÷ 5 = 7d and 25 ÷ 5 = 5
∴ The length of one side = 7d - 5
Daryl's expression is 7d - 5
Now lets check the answers
a. 35d - 25 ⇒ No
b. 7d - 15 ⇒ No
c. 5(35 - 25) ⇒ No
d. -5 + 7d ⇒ Yes
e. (35d - 25) ⇒ No
The equivalent expression to Daryl's expression is -5 + 7d

Answer:
6850 & 650
Step-by-step explanation:
The question is partly incomplete as it didn't state the cost of ticket sold. Also, it didn't state the total number of tickets sold. But, assuming that the tickets sold were $15 and $25 tickets, and the total number of tickets sold was 7500, then we say that
Let x = the number of $15 tickets sold
Let y = the number of $25 tickets sold
x + y = 7500 y = 7500 - x
15x + 25y = 119000
15x + 25(7500-x) = 119000
15x + 187500 - 25x = 119000
-10x = -68500
x = 68500 / 10
x = 6850 tickets at $15 each
Remember from the first calculation, we said x + y = 7500, then
y = 7500 - 6850
y = 650 tickets at $25 each
All you have to do is substitute the values I assumed for your given value. Thanks
The height of the fence is irrelevant. The bottom of the ladder is 3+8 = 11 feet from the building. The window is 14ft above the ground:
sqrt(14^2+11^2) = length of your ladder.
