Answer

6,122 hm

Explanation

You can carry out operations on the like terms only. So convert all units to one unit.

I will convert them to dam

1 km =100 dam

73 km = 73 × 100

=7,300 dam

11 km = 11× 100

1100 dam

1 hm = 10 dam

47 hm = 47 × 10

= 470 dam

55 hm = 55× 10

= 550 dam

73km 47hm 2dam - 11km 55hm = (7300+ 470+2) - (1100+550)

= 7,772 - 1,650

= 6,122 hm

Find a quadratic equation whose roots are 1.5 +√2 and 1.5-√2expressing it in the form of ax^2+bx+c+c=0 where a,b and c are integ

Ilia_Sergeevich [38]

0 = f(x) = (x - r)(x - s) = x² - (r+s) + rs

We have r=1.5+√2, s=1.5 -√2 so r+s = 3 and

rs = (1.5+√2)(1.5 - √2) = 1.5² - (√2)² = 2.25 - 2 = 0.25

f(x) = x² - 3x + -.25

For integer coefficients we mulitply by 4,

g(x) = 4f(x) = 4x² - 12x - 1

Answer: 4x² - 12x - 1 = 0
