Answer:

x = 9

Step-by-step explanation:

The angles in red are equivalent and the triangle is isosceles.

This means the sides with lengths 12 and x + 3 are equivalent.

x + 3 = 12

x + 3 - 3 = 12 - 3

x = 9

The area of a square room is 16x^2+72x+81. what is the length of one side of the room

maxonik [38]

To find this you know that the A of a square = s^2

So the length of one side equals $s = \sqrt{16 x^{2} +72x+81}$

Since this is a perfect square, it would equal $A = (4x+9)^{2}$

And $s = \sqrt{(4x+9)^{2}} = 4x+9$

Also you know it is a perfect square because the first and last terms are perfect squares :) :D
