Answer:
So let us call the shorter side, i.e the width: 'x'
So each length is four times the width = 4x
The perimeter consists of two widths and two lengths and equals 50 inches.
So:
x+x+4x+4x=50
solve for x:
10x = 50
to find x divide both sides by 10:
10x/10 = 50/10
x=5
So width equals 5 in and length is four times this i.e. 4x5=20
To check: 5+5+20+20=50 !!!!

Answer:
(-2,4)
Step-by-step explanation:
This implies 
.
This means 
and 
.
Subtract 3 on both sides for first equation: 
.
Add 3 on both sides for the second equation: 
.
So the pre-image (x,y) is (-2,4) if the image is (1,1).
Let's check:
So the solution has been checked and verified.
Diide both sides by -1
|j|=9
rememeber if |a|=b, then assume a=b and a=-b
so
j=9 and j=-9
