Answer:

(x - $\frac{5}{2}$ )² + $\frac{7}{4}$

Step-by-step explanation:

x² - 5x + 8

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 5x

x² + 2(- $\frac{5}{2}$ )x + $\frac{25}{4}$ - $\frac{25}{4}$ + 8

= (x - $\frac{5}{2}$ )² - $\frac{25}{4}$ + $\frac{32}{4}$

= (x - $\frac{5}{2}$ )² + $\frac{7}{4}$

Identify the height of a triangle in which b=(x−2) m and A=(x2−4) m2. A) h = (2x + 4) m B) h = (2x + 2) m C) h = (x + 2) m D) h

hjlf

Answer:we know that

area of triangle=b*h/2

b=(x-2) m

Area=(x²-4) m²

h=?

(x²-4)=(x+2)*h/2

but remember that

(x²-4)=(x+2)*(x-2)

subsititute

(x+2)*(x-2)=(x+2)*h/2

(x-2)=h/2

h=2*(x-2)

the answer is

the height of a triangle is 2*(x-2)
