What are the solutions to the quadratic equation 4x2 = 64?

Karolina [17]

<h2>Greetings!</h2>

Answer:

x = −4 and x = 4

Step-by-step explanation:

4x² = 64

Lets get x² on its own. To do this we divide each sides by 4:

x² = 16

Now to get just x, we need to square root this answer:

√x² = √16

x = √16

x = 4

But this can be ±4 as it -4 and 4 squared both give 16.

So your answer is x = −4 and x = 4

What is the volume of a box that can fit exactly 128 1/8 inch cubes with 1/2 inch sides?

$\bf \textit{the volume of one small cube is }V=\left( \frac{1}{2} \right)\left( \frac{1}{2} \right)\left( \frac{1}{2} \right)\implies V=\cfrac{1}{8}
\\\\\\
\textit{now, the box fits in }128\frac{1}{8}\textit{ of those cubes, thus its volume is}
\\\\\\
128\frac{1}{8}\cdot \cfrac{1}{8}\implies \cfrac{128\cdot 8+1}{8}\cdot \cfrac{1}{8}\implies \cfrac{1025}{8}\cdot \cfrac{1}{8}\implies \cfrac{1025}{64}\implies 16\frac{1}{64}~in^3$
