\bf \begin{cases}
x=3\implies &x-3=0\\
x=-4\implies &x+4=0\\
x=7\implies &x-7=0
\end{cases}
\\\\\\
(x-3)(x+4)(x-7)=\stackrel{y}{0}\implies \stackrel{FOIL}{(x^2+x-12)}(x-7)=y
\\\\\\
x^3+x^2-12x-7x^2-7x+84=y\implies x^3-6x^2-19x+84=y

Emily's vacuum cleaner has a power rating of 200 watts. If the vacuum cleaner does 360000 joules of work, how long did Emily spe
MakcuM [25]
To answer this, we need to know the formula of the relationship between the work and the power rating and time.

The formula is:
E(J)<span> = </span>P(W) ×<span> t</span><span>(s)
</span>360000 = 200 * t
t = 360000 / 200
t = 1800 s

So, Emily will spend 1800 seconds in vacuuming. It is also equivalent to 30 minutes.

What is the area of the square
ahrayia [7]

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.
