Case A : x=2, y=-5
so putting the values of x and y in the equation, we get 10y -3x should be -11
so, 10* (-5) - 3 *2 = -50-6 = -56
case B , value of equation = 10*4 - 3*1 = 37
case C, value of equation = 10*6 -3*16.3 = -11.1
Case D, value of equation = 10*8-3*23 = 11
Ans will be C
You need a length and width for it

Step-by-step explanation:
Answer:
The expression of the other side of the rectangle = 2x + 4y + 25
Step-by-step explanation:
The Perimeter of the rectangle is 12 x + 8y
The one side of the rectangle is 4x - 25
Let the other side of the rectangle be S
Now, the PERIMETER OF THE RECTANGLE = 2 ( SUM of BOTH SIDES)
⇒ 12 x + 8y = 2(S + (4x - 25))
or, 12 x + 8y = 2S + 8 x - 50
or, 12 x + 8y - 8x + 50 = 2S
⇒ 4x + 8y + 50 = 2S
or, S = 2x + 4y + 25
Hence, the expression of the other side of the rectangle = 2x + 4y + 25
