22 = z + (-9) Switch the sides
z = 22 - (-9) Solve
z = 31 So, z = 31
n would equal <em>-33</em>.
<em>n=-33</em>
Answer:
The new area is 1800feet^2
Step-by-step explanation:
Step one:
Given data
The length and width or a rectangular courtyard is 40 feet and 30 feet
we can calculate the area of the courtyard as
Area= 40*30
Area= 1200 feet^2
when the extra 15 feet is added to the width
the new width is= 30+15= 45feet
The new area is
Area= 40*45
Area= 1800 feet^2
in all the area will increase by 1800-1200= 600feet
5x = 25
x = 5
