1. This triangle is scalene.
2. This triangle is isosceles. Two angles are equal.
3. This triangle is equilateral, all sides are equal.
4. This triangle is equilateral, all angles are equal.
Answer:
its c
Step-by-step explanation:
i had the same question on my test
In a right angled triangle we can use Pythagoras theorem to determine third side in case two sides are given.
The formula of Pythagoras theorem is given by:

Where x , y and z are sides of triangle , z is hypotenuse.
Now we use this formula to find hypotenuse.
Plugging other two sides which are 5 in. and 12 in.



Taking square root on both sides
square root of 169 is 13
so we have z=13
Hypotenuse is 13 inches.
we have

Equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side.


the factorization is equal to

therefore
<u>the answer is</u>

Answer:
n² + 3
this is the expression
