Answer:

1st, keep value of x in 1st equation

Step-by-step explanation:

-6(-2y-1)+2y=48

14y=48-6

y=42/14

y=3

Find the area and perimeter of a rectangle.<br> the length is x+6 the width is x+2
yarga [219]

Answer:

<h2><u><em>Area = x² + 8x + 12</em></u></h2><h2><u><em>Perimeter = 4x + 16</em></u></h2>

Perimeter

2 × (x + 6 + x + 2) =

2 × (2x + 8) =
