A painting is 20 cm wider than the height and 576 cm² write a representation using variable x ​

For x = height:

x(x + 20) = 576.

Step-by-step explanation:

The area is 576 cm^

Area = width * height

Let the height be x,  then the width is (x + 20) cm

So the expression for the area can be written

x(x + 20) = 576.

x²   +  20x  -  576  =  0

Step-by-step explanation:

If x is height:

 width = (20 + x)

         area = width  x  height

         576  =  (20 + x)     x      x

         576  =  20x   + x²

      ∴ x²   +  20x  -  576  =  0

answer: procent 54 wynosi 33,33%

the answer is (-4,-4)

hope this ! : d
