Answer:
Correct option: C.
Step-by-step explanation:
(Assuming the correct function is R(x) = 2x^2 + 3x + 5)
To find the input value that gives the value of R(x) = 19, we just need to use this output value (R(x) = 19) in the equation and then find the value of x:
Solving this quadratic function using the Bhaskara's formula (a = 2, b = 3 and c = -14), we have:
So looking at the options, the input to the function is x = 2
Correct option: C.

<h3>Area of a square</h3>
A square is quadrilateral with 4 sides. The formula for calculating the area of the shape is given as:
A = L²
Given the following parameters
A = 
Substitute
L²
Determine the perimeter
Perimeter = 4L
Perimeter = 4(14x^6y^5z^3)
Perimeter =
Hence the perimeter of the room will be feet
