I"m guessing you mean

add 5 to both sides

square both sides
x+9=x²+18x+81
minus x+9 both sides
0=x²+17x+72
factor
what 2 numbres multiply to get 72 and add to get 17?
8 and 9
0=(x+8)(x+9)
set to zer
0=x+8
x=-8
x+9=0
x=-9
test each


1-5=-4
-4=-4
true


-5=-5
true
the solutions are x=-9 and -8
Lifting a piece of furniture and moving it to the right. Since all of the forces aren't going the same direction, no work is being done.
For this case we have two functions of the form y = f (x). We must find the quotient of the following functions:

So, we have by definition:

Answer:

with 3x + 5 different from zero, so that the function is defined
Answer:
2^2 +5^2 = c^2
Step-by-step explanation:
We can use the Pythagorean theorem to solve for c
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
2^2 +5^2 = c^2
4+25 = c^2
29 =c^2
