Answer:
(x-3) (x+10)
Step-by-step explanation:
18 + 81 = 9(x²<span> + 6x + 9)
</span><span>11 = (x + 3)</span>²
When we are completing the square, we are going to move the value of c across the equals. We will do that by adding, and end up with
18=9(x²+6x)
We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9
This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)
Dividing both sides by 9, we have:
11=x²+6x+9
11=(x+3)²
(c+9)² = 64
c+9 = +/-√64
c+9 = 8 and c+9=-8
c= - 1 and c= -17

Answer:
9-4=5
Step-by-step explanation:
For this case we have that the total of objects is given by:
Large blue objects, small blue objects, large red objects and small red objects.
In total we have: 
0 objects.
If we want to find the probality of obtaining small and blue objects we have to:
