Answer:
56 - 6√12
Step-by-step explanation:
If s = side length = √2 - 3√6, then:
A = area of square = s² = (√2 - 3√6)²
= (√2 - 3√6)(√2 - 3√6)
= 2 - 3√12 - 3√12 + 9(6)
= 2 - 6√12 + 54, or
= 56 - 6√12 is the area of the square.

Answer: (5,10)
Step-by-step explanation:
multiply first equation with 2 and add it to second to eliminate X
7x-5y=-15 //*2
14x-10y=-30
-14x+7y=0
----------------
-3y=-30
y=-30/-3
y=10
7x=50-15
7x=35
x=35/7
x=5
Answer:
8
Step-by-step explanation:
The shortest leg warmer:
