vichka [17]

Answer:

infinite solutions

Step-by-step explanation:

x+6+8=2x-x+14

x+6+8=x+14

x+14=x+14

14=14

or

In triangle ABC, a=7, b=3 and cos C = 1/2. The value of c is
aalyn [17]

Answer:

Correct option: 2 -> sqrt(37)

Step-by-step explanation:

To solve this problem, we just need to use the law of cosines. This law is used to find the third side of a triangle, when we have the two other sides and the angle between them.

The equation of the law of cosines is:

c^2 = a^2 + b^2 - 2 * a * b * cos(C)

So, we have that:

c^2 = 7^2 + 3^2 - 2 * 7 * 3 * (1/2)

c^2 = 49 + 9 - 21

c^2 = 37

c = sqrt(37)

Correct option: 2

Why is 2 the only even prime number
Temka [501]

Answer:

<em>A prime number is a whole number greater than 1 whose only factors are 1 and itself</em>

two is the only even prime number because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two.
