hypotenuse²=base²x height²
Step-by-step explanation:
It is used to find the third side of a triangle.
Hope it helps :)
The area of the triangle is 14.625.... in order to find the area of a triangle just use this formula b×h÷2

Number 1 is x=8!!
2 is pretty confusing so I hope someone else can answer two as I have answered 1!
(x + y)^2 = (x^2 - 2xy + y^2)
First distribute the ^2 on the left side of the equation to each term inside the parenthesis:
x^2+ 2xy + y^2
Now pick one of the variables to solve for and isolate it:
(solving for x)
x^2 + 2xy + y^2 = x^2 - 2xy + y^2
x^2+ 2xy = x^2 - 2xy
2xy = -2xy
-x = x
x = 0
When you solve for y in the equation it will turn out to be 0 as well
