The distance from the top of the mirror to the ceiling once the mirror is hung on the wall is 21 inches
The dimension of the mirror is given as:
From the center of the mirror to the floor of the wall, the distance is:
So, the distance to the top of the mirror will be:
Substitute 24 for height
Convert feet to inches
The distance from the top of the mirror to the ceiling is the difference between the height of the wall and 75 inches.
So, we have:
Convert feet to inches
Hence, the distance is 21 inches

Answer:
C is correct
Step-by-step explanation:
Given: System of linear inequality
First we will draw the graph of system of equation and then see the correct option.
Equation 1:
We will make the table.
x : -2 0 2
y : 1 0 -1
Test Point: (0,4)
0<-2 ( False )
Shaded area away from (0,4)
Equation 2:
We will make the table.
x : -2 0 2
y : -1 3 7
Test Point: (0,4)
4≥3 ( True )
Shaded area towards (0,4)
Please see attachment for graph.
Hence, C is common shaded area (region)
Write the word problem in algebraic form:
n2 -14 = 5n
Write as a quadratic:
n2 - 5n - 14 = 0
Factor:
(n+2)(n-7) = 0
Solve:
n+2 = 0 => n = -2
n-7 = 0 => n = 7
positive solution is 7. (14 less than 72 = 35 which is also 5 times 7)
