Answer:

k=5

Step-by-step explanation:

$f(x)=x^2-6x+14$

$(\frac{b}{2} )^2= (\frac{-6}{2})^2= (-3)^2=9$

$f(x)-5=x^2-6x+9$

$f(x)-5=(x-3)^2$

$f(x)=(x-3)^2+5$

$k=5$

The two triangles shown have the same perimeters. What is the perimeter of each triangle

Shkiper50 [21]

Answer:

28 units

Step-by-step explanation:

Since the perimeter of both triangles is same,

the sum of all sides of first triangle = sum of all sides of second triangle

or, 6x + 3 + 2x + 4x = 5x + 5x + 3x + 2

or, 12x + 4 = 13x + 2

or, 4-2 = 13x - 12x

or, 2 = x

Now,

Putting the value of x in the perimeter of first triangle,

12x + 4= 12* 2+ 4

= 28 units
