20 units
Perimeter =add up all sides.
Perimeter = 5+1+5+9
=20 units
The answer is 2.6 because 2.6+2=4.6
Xy=30
x=6/11
6/11y=30
Divide by 6/11 on both sides
y=55

Answer:
x = 1/5
Step-by-step explanation:
5(3x + 4) = 23
Distribute
15x+20 = 23
Subtract 20 from each side
15x+20-20 = 23-20
15x = 3
Divide by 15
15x/15 = 3/15
x = 1/5
