Step-by-step explanation:
(x+6)(x+3)=9+(x+1)
= x^2+3x+6x+18
=x^2+9x+18=9(x+1)
=x^2+9x+18=9x+9
tbs = to both sides
(-9x tbs)= 9x-9x=0 so x^2+18=9
(-18tbs) = x^2=9-18 becomes x^2=-9
x=

Step-by-step explanation:
To solve for <em>CD</em>, we can create a right triangle.
Where <em>CD</em> becomes the hypotenuse.
The length of the base of the triangle is 9 units.
The length of the height of the triangle is 5 units.
Apply Pythagorean theorem to solve for the hypotenuse.
