Question

Which expressions are equivalent to 36y−18x−108y+54 ?

Answer 1

Answer:

Doubling the Area of a Given Square. Why it works: The area of the original square is AB^2, so we want a square of area 2AB^2. If the side of the new square is s, then we want s^2 = 2AB^2, or s = AB*sqrt(2), which is the length of the diagonal of the square.

Answer 2

Step-by-step explanation:

For this case we must find an expression equivalent to:

36y-18x-108y + 5436y−18x−108y+54

We add similar terms:

36y-108y-18x + 54 =36y−108y−18x+54=

Different signs are subtracted and the sign of the major is placed:

-72y-18x + 54−72y−18x+54

Thus, an equivalent expression is:

\begin{gathered}-72y-18x + 54\\-18x-72y + 54\end{gathered}

−72y−18x+54

−18x−72y+54

Answer:

-18x-72y + 54−18x−72y+54
