Area = Length x Width
Given that length = 192cm² and the length = 12 cm, we plug these values into the equation and solve for the width:
192 = 12 x width
192 = 12width
width = 192 ÷ 12
width = 16 cm
Answer: Width = 16 cm

Answer:
(-1,3)
Step-by-step explanation:
–2x – 9y=-25
-4x – 9y=-23
Multiply the second equation by -1
4x + 9y=23
Add this to the first equation
–2x – 9y=-25
4x + 9y= 23
-----------------------
2x = -2
Divide each side by 2
2x/2 = -2/2
x = -1
Now we need to find y
4x+9y = 23
4(-1) +9y = 23
-4 +9y = 23
Add 4 to each sdie
-4+4 +9y = 23+4
9y = 27
Divide each side by 9
9y/9 = 27/9
y =3
R = 5n + 5w
r - 5w = 5n
r/5 - w = n
