The perimeter of triangle is 30ft.
Step-by-step explanation:
First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :



Let b = 12,
Let c = 13,



Next you have to find the perimeter of triangle by adding all the sides together :

Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)
