2r + 2s = 50

2r - s = 17

-----------subtract

3s = 33

s = 11

2r - s = 17

2r - 11 = 17

2r = 28

r = 14

so r = 14 and s = 11

svetlana [45]

Answer:

4(R + 5 + R + 2) [Option B]

Step-by-step explanation:

<u>GIVEN :-</u>

  • Length = R + 5
  • Width = R + 2

<u>TO FIND :-</u>

  • Perimeter of the rectangle

<u>FORMULAE TO BE USED :-</u>

For a rectangle with length 'l' and width 'w' , its perimeter = 4(l + w)

<u>SOLUTION :-</u>

Perimeter = 4(R + 5 + R+2)

-7x - 2y = 19<br> 4x + y = -12<br> Solve the system
nalin [4]

-7x - 2y = 19

4x + y = -12

Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)

-7x - 2y = 19

8x + 2y = -76

Add equations together

x = -52

Plug x value into an equation

4(-52) + y = -12

Solve for y

-208 + y = -12

y = 196

Hope this helps! ;)
