Asquare concert stage in the center of a fairground has an area of 4x^2 + 12x +9 ft^2. the dimensions of the stage have the form cx+d where c and d are whole numbers. find and expression for the perimeter of the stage. what is the perimeter when x = 2 ft?

(8x+12) feet.The perimeter when x=2ft is 28 feet.

Step-by-step explanation:

The solution is in the attached file.

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
