Answer:a^2-b^2=3

Step-by-step explanation:

We need to find the value of the below expression i.e.

a^2-b^2 when a = 2 and b = 1.

So,

Put a = 2 and b = 1 in the above expression. So,

a^2-b^2=(2)^2-1^2\\\\=4-1\\\\=3

Hence, the value of the expression is equal to 3.

A manufacturer makes rectangular blankets in several styles and sizes. The outline of a popular blanket in size A is shown below
nikdorinn [45]

Answer:

(10x + 8) is the polynomial expression for the perimeter of the blanket.

Step-by-step explanation:

The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.

Now, the perimeter of a rectangle having height h and width w is given by  

P = 2h + 2w

⇒ P = 2(2x - 3) + 2(3x + 7)

⇒ P = 4x - 6 + 6x + 14

⇒ P = 10x + 8.

So, this is the polynomial expression for the perimeter of the blanket. (Answer)
