Let
x--------> the border’s length
y--------> the border’s width
P--------> perimeter of the border
we know that
x=5+y------> equation 1
P=2*[x+y]-----> P=2x+2y
P <=180 ft
(2x+2y) <= 180-------> equation 2
substitute the equation 1 in equation 2
2*[5+y]+2y <= 180
10+2y+2y <= 180
4y <= 180-10
4y <=170
y <=42.5 ft
so
the maximum value of the width is 42.5 ft
for y=42.5 ft
x=42.5+5------> x=47.5 ft
the answer is
the width of the border is less than or equal to 42.5 ft
Given statement is "You download 12 new songs to your MP3 player. then you delete 5 old songs."
We have to write each amount as an integer.
Download 12 new songs means you are adding number to your MP3 player so we will use + sign for 12
So the amount in integer form will be +12
Ddelete 5 old songs means you are subtracting number from your MP3 player so we will use - sign for 5
So the amount in integer form will be -5
combining both expressions we can write final statement as:
+12-5
Which can be simplified to +7.
Answer
10 ft sides
Step-by-step explanation:
Since its squared the easiest way to figure out the sides is to square root the area and square root of 100 is 10
