and
Step-by-step explanation:
The correct equation is:
To solve by completing the square method.
Solution:
We have:
In order to solve by completing the square method we will carry out the following operations to the given equation to get a perfect square binomial.
We can write as:
[As
]
Adding both sides by
Taking LCD to add fraction.
Taking square root both sides.
Subtracting both sides by :
So, we have:
and

(Answer)
Não, não podemos fazer um triângulo com os comprimentos dos lados de 2 cm, 3 cm e 10 cm. Isso ocorre porque a soma de 2+3 < 10. (in english: No, we cannot make a triangle with the side lengths of measurement 2 cm, 3 cm, and 10 cm. This is because sum of 2+3 < 10).
<h3>What is triangle inequality theorem?</h3>Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,
Now, for this case, the sides given are:
- a =2 cm,
- b = 3 cm,
- and c = 10 cm
But we see that:
a+ b = 5 cm which is < c which is of 10 cm.
Thus, these lengths don't satisfy the triangle inequality theorem, and therefore, cannot be sides of any triangle.
