Hello,

\sqrt{x} - \sqrt{y} = (\sqrt[4]{x}+ \sqrt[4]{y} )( \sqrt[4]{x} - \sqrt[4]{y} )=72\\\\
\sqrt[4]{x}- \sqrt[4]{y}=6\\\\
(\sqrt[4]{x}+ \sqrt[4]{y})*6=72\\\\
\sqrt[4]{x}+ \sqrt[4]{y}=12 \\ 
\sqrt[4]{x}- \sqrt[4]{y}=6 \\\\
2 \sqrt[4]{x}=18==\textgreater\sqrt[4]{x}=9==\textgreater\ x=6561\\
2 \sqrt[4]{y}=6==\textgreater\sqrt[4]{y}=3==\textgreater\ y=81\\



Proof:
\sqrt[4]{6561} - \sqrt[4]{81} =9-3=6\\\\
 \sqrt{6561} - \sqrt{81} =81-9=72

Vinyl peel and-and-stick floor tiles are each 1- foot square. What is the minimum number of these tiles needed to tile the entir
Anna [14]

Answer:

The minimum number of Vinyl peel and stick floor tiles needed is 216 Tiles

Step-by-step explanation:

Here we have area size of Vinyl peel and stick floor tiles = 1 ft²

Size of floor of rectangular room = 12 ft × 14 ft = 168 ft²

Size of floor on rectangular hallway = 12 ft × 4 ft = 48 ft²

Total area of floor in rectangular room and rectangular hallway

= 168 ft² + 48 ft² =  216 ft²

Therefore number of Vinyl peel and stick floor tiles needed =

(Total area of floor in rectangular room and rectangular hallway)÷( Area size of Vinyl peel and stick floor tiles) = 216 ft²/(1 ft²) =  216

Therefore the minimum number of Vinyl peel and stick floor tiles needed =  216 Tiles.

En una oficina hay 96 computadores en total. La razón entre los computadores que deben ser reparados y aquellos que se encuentra
Alik [6]

Answer:

36 computadores deben ser reparados.

Step-by-step explanation:

Dado que en una oficina hay 96 computadores en total, y la razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3:5, para determinar cuántos computadores de la oficina deben ser reparados en total se debe realizar el siguiente cálculo:

(96 / (3+5)) x 3 = computadores que deben ser reparados

(96 / 8) x 3 = computadores que deben ser reparados

12 x 3 = computadores que deben ser reparados

36 = X

Por lo tanto, 36 computadores deben ser reparados.

H + 86.43 = 531.79<br><br> h = ___________
dedylja [7]
H= 445.36
because you bring the 86.43 over to the 531.79. which would make 86.43 a negative number. so you subtract 531.79 by 86.43
