Let n be the amount of time it takes for them to shampoo the carpet together. Then:
1/3+1/6=1/n
2n+n=6
3n=6
n=2 hours to shampoo the carpet together

The quadratic equation which matches given solution is x² + 3x + 3 = 0. Then the correct option is C.
<h3>What is a quadratic equation?</h3>
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
We know that the formula
The solutions are given below.
Then
1) 2x² + 6x + 9 = 0, the zeroes of the equation will be
2) x² + 3x + 12 = 0, the zeroes of the equation will be
3) x² + 3x + 3 = 0, the zeroes of the equation will be
4) 2x² + 6x + 3 = 0, the zeroes of the equation will be

Answer:
(n+4)(n+22)
Explanation:
Use FOIL
First - multiply n•n and get n2
Outside - multiply n•22 and get 22n
Inside - multiply 4•n and get 4n
Last - multiply 4•22 and get 88
You should have n2+22n+4n+88
Then add like terms so 22n+4n and get 26n
You would get n2+26n+88
Answer:
-9t
Step-by-step explanation:
-3t -6t
using multiplication of signs
-×-=+
so add the numbers because they have the same
coefficient
-3-6= -9
so
-3t-6t=9t
