The perimeter of a rectangle is 40 inches. If the length of the rectangle is 15 inches, which equation could be used to find the

width, x?
OA. x + 2(15) = 40
OB. 15(x + 2) = 40
O.Cx+ 15 = 40
OD. 2(x + 15) = 40

<h2><u>A</u><u> </u><u>N</u><u> </u><u>S</u><u> </u><u>W</u><u> </u><u>E</u><u> </u><u>R</u><u> </u><u>:</u></h2>

  • Perimeter of rectangle = 40 inches
  • Length of rectangle = 15 inches

Let the required Breadth of rectangle be 'x' inches

Perimeter of rectangle is calculated by the given below formula :

  • Perimeter = 2(Length + Breadth)

Now, substitute the given values in above formula :

→ 40 = 2(15 + x)

<u>Hence</u><u>,</u><u>the</u><u> </u><u>optio</u><u>n</u><u> </u><u>(</u><u>d</u><u>)</u><u> </u><u>2</u><u>(</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u><u>5</u><u>)</u><u> </u><u>=</u><u> </u><u>4</u><u>0</u><u> </u><u>is</u><u> </u><u>the</u><u> </u><u>corre</u><u>ct</u><u> </u><u>answer</u><u>.</u>

−9x+4y=6 9x+5y=−33 ​

Answer:

{x,y} = {-2,-3}

Step-by-step explanation:

System of Linear Equations entered :

  [1]    -9x + 4y = 6

  [2]    9x + 5y = -33

Graphic Representation of the Equations :

   4y - 9x = 6        5y + 9x = -33  

Solve by Substitution :

// Solve equation [2] for the variable  y  

 

 [2]    5y = -9x - 33

 [2]    y = -9x/5 - 33/5

// Plug this in for variable  y  in equation [1]

  [1]    -9x + 4•(-9x/5-33/5) = 6

  [1]    -81x/5 = 162/5

  [1]    -81x = 162

// Solve equation [1] for the variable  x  

  [1]    81x = - 162  

  [1]    x = - 2  

// By now we know this much :

   x = -2

   y = -9x/5-33/5

// Use the  x  value to solve for  y  

   y = -(9/5)(-2)-33/5 = -3
