The equation which is used to determine x, the width of the window is,
. Option B shows the correct expression for width x of the window.
<h3>
What are length and width?</h3>
Length is describing how long is the object. The width is defined as how wide is the object.
Given that the width of the window is 4.9 feet. The length is given as 0.6 feet less than 2.5 times its width.
The height of the window is given as,

The other height of the window is given as,

When equating both equations, we get,

Therefore, an equation which is used to determine x, the width of the window is,
. Option B shows the correct expression for width x of the window.

Answer:
Following are the solution to the given question:
Step-by-step explanation:
Whenever she began to drive farther east, at 70 km per hour, Prachi was 5 km east of her home.
Let f(n) at the beginning of her nth hour drive be Prachi's distance to her home.
f is a sequence of arithmetic.
Write a series explicit form.

-7x-5y=5
-(-9x-5y)=15 It's minus because negative times negative = positive
2x=-10
x= -5
-7(-5) - 5y = 5
35-5y =5
-5y = -30
y=6
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters
