The price quote formula for this problem is P = 4R + 8B + 25.
Hence option B is correct.
Use the concept of forming of equation defined as:
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Given that,
Devon owns a house cleaning company.
He calculates his price quotes for potential customers using a specific formula.
The formula includes a $25 base charge.
He adds $8 for each bathroom (B).
He adds $4 for each other room (R).
The objective is to determine which formula represents Devon's price quote calculation.
If R represent the number of rooms
Then cost of R room = 4R
If B represents the number of bathrooms
Then cost for B bathroom = 8B
The base charge is 25
Then the total charge is = 4R + 8B + 25
Hence,
The price quote formula for this problem is P = 4R + 8B + 25 which is option B.

I don't know how to get the third side.
Without information about the angle between the two sides of the triangle, the third side's length can only be estimated to be between 13 and 25 feet.
In mathematics, you can often use the Pythagorean theorem to find the length of the third side of a triangle. This theorem, which applies to right triangles, states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In your case, however, without any information concerning the angle between these two sides, we cannot determine a unique value for the length of the third side. The third side will have a value that lies between 13 ft and 25 ft, depending on the angle between the two sides.

Answer:
3 hours
Step-by-step explanation:
Given that:
Time taken by Kalon = 4 hours
Time taken by Marna =?
Time taken if the work together = 1 5/7 hours
Kalon's rate = 1/ time =. 1/4
Kalon + Marna = 1 ÷ 1 5/7 = 7/12
Hence,
Marna's rate = 7/12 - 1/4
Marna's Rate = (7 - 3) / 12 = 4/12 = 1/3
Marna's rate = 1/3
Hence, time it takes Marna = reciprocal of rate = 1÷ 1/3 = 1 * 3/1 = 3 hours
