Answer 1

Answer:  In the expression , $x^2+15x$

The area of the photo = $x^2$ ( the second degree term, of the expression $x^2+15x$ )

The area of the frame around the picture = 15x ( the first degree term of the expression )

The length of the frame = x + 15 cm, ( the binomial, (x+15), a factor of expression $x^2+15x$ ) 

The length of the photo = x, ( the monomial, x, a factor of expression $x^2+15x$ )

Step-by-step explanation:

Here x represents the length of the photo,

While the length of the frame is 15 more than that of photo,

⇒ Length of the frame = (x+15) cm,

Since, the photo is of square shape,

⇒ Area of the photo = $x^2$ square cm

Also, the breadth of the frame = x cm,

And, frame is of rectangular shape,

⇒ Area of the frame = (x+15)×x = $x^2+15x$  square cm

Also, the length of the fram around the picture = 15 cm

And, the breadth of that area = x cm

⇒ The area of the frame around the picture = 15x square cm
