The area of a rectangular room is 750 square feet. the width of the room is 5 feet less than the length of the room. which equations can be used to solve for y, the length of the room?

Width=25 ft and length=30 ft

Step-by-step explanation:

In order to find the answer let's remember that the area (A) of a rectangle is:

Let's assume that the length of the room is 'X' feet.

Becuase the problem mentioned that the width (Y) of the room is 5 feet less than the length, then:

Now, using the area equation we have:

A=width*length

but using the width expression we have:

Using the root's equation we have:

Because the length (X) can't be negative, then length=30 feet. In order to find the width we have:

So the width is 25 feet.

In conclusion the room has a width=25 ft and length=30 ft.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
