The blueprint for Jessica’s new room has a scale that states every ½ inch is equal to 15 inches. If this blueprint shows the length of her new room to be 3 inches, what will be the actual length of her new room?

Her room is 90 inches.

Step-by-step explanation:

1/2 x 6 = 3

If we multiply 1/2 by 6, then we must do the same to 15.

15 x 6 = 90.

Given:

A quadratic equation is

To find:

The standard form of the given equation and find the value of c.

Solution:

The standard form of a quadratic equation is

              ...(i)

We have,

It can be rewritten as

           ...(ii)

On comparing (i) and (ii), we get

Therefore, the value of c is equal to 5 and the correct option is C.
