Answer:

The two 50ml bottles

Step-by-step explanation:

(I will be using the $ but just change the sign to the euros)

$55/80ml= .68 per ml

45+22.5= $67.5

67.5/100 is about $.67

Therefor the two 50ml bottles is cheaper per ML and you get more product

Help pleaseeeeeeeeee

Answer:

  47 -6√10

Step-by-step explanation:

As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.

  (a -b)² = a² - 2ab + b²

  (√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²

  = 2 - 6√10 + 3²(5)

  = 47 -6√10

__

<em>Check</em>

  √2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals

  (√2-3√5)² ≈ 28.02633

  47 -6√10 ≈ 28.02633
