Cuboid has 6 faces. If each face was 2m squared, that would be 2m squared times 6 which is 12m squared
In general, the scalar multiple of k times u,<span> is this:
</span>
So, here's how we find
The answer is <span><span>(6,12).</span></span>
Rectangle, triangle, and I believe square
Complete the square:
<span>y = 3x^2 - 12x + 4 </span>
<span>y = 3(x^2 - 4x) + 4 </span>
<span>y = 3(x^2 - 4x + 4 - 4) + 4 </span>
<span>y = 3(x^2 - 4x + 4) - 12 + 4 </span>
<span>y = 3(x - 2)^2 - 8</span>
