Mkey [24]

Answer:

D. Continue cutting smaller and smaller slices.

Step-by-step explanation:

While, in theory, this could be a step, it would be a pointless one. You would have to eventually rearrange the pieces, but now there would be more of them.

Hope this helps!

Solve x ^ 2 - 3x = - 8 using the quadratic formula.
Sergio039 [100]

Answer: \frac{3 +- \sqrt{23}i}{2} If using complex numbers, or undefined if using all real numbers

Step-by-step explanation:

Moving -8 to the left side of the eq by adding both sides by 8=

x^2-3x+8=0

The quad formula:\frac{-b  +- \sqrt{b^2-4ac}}{2a}

a=1 b=-3 c=8

Inserting a b c values into formula: \frac{-(-3)  +- \sqrt{(-3)^2-4(1)(8)}}{2(1)}

Simplifying: \frac{3 +- \sqrt{9-32}}{2}

\frac{3 +- \sqrt{-23}}{2}  Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.

OR

\frac{3 +- \sqrt{23}i}{2} Using complex numbers i, to replace the negative number created by subtracting 9-32.
