Answer:
x+y+3w
Step-by-step explanation:
If you are saying that the hypotenuse is 10 cm the you have to solve the following equation using the Pythagorean theory.
4^2 + b^2 = 10^2
16 + b^2 = 100
16 - 16 + b^2 = 100 - 16
b^2 = 84
Find 
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10 |subtract 2 from both sides
3x = 5x - 12 |subtract 5x from both sides
-2x = -12 |divide both sides by (-2)
x = 6

Answer:

Step-by-step explanation:
Quadratic formula:
when the equation is 
The given equation is
. Let's first arrange this so its format looks like
:


Subtract 1 from both sides of the equation

Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:
