Answer:

$8 \sqrt{72} = 8 \sqrt{3 \times 3 \times 2 \times 2 \times 2} \\ = 8 \times 3 \times 2 \times \sqrt{2} = 48 \sqrt{2}$

<h2>48√2 is the right answer.</h2>

I need help with this I need this done tomorrow please answer need help heart attack

Nataliya [291]

Basically what you have to do is multiply the two numbers that are mentioned and that will be your answer.

This is because the item will have the same amount or length and you just need to find what it will be with multiple ones.

Next time you could highlight keywords that help you understand if you are supposed to multiply, divide, subtract, or add.

Find the dimensions of the rectangle of largest area that has its base on the x-axis and its other two vertices above the x-axis

USPshnik [31]

If one of the vertices on the x-axis is (x, 0), then the other vertex on the same axis is (-x, 0), so that the rectangle has base 2x. The other two vertices on the parabola are the points (x, 6 - x²) and (-x, 6 - x²), so the height of the rectangle is 6 - x².

Then the area of the rectangle is given by the function

$A(x)=2x(6-x^2)=12x-2x^3$

Compute the critical points of A:

$A'(x)=12-6x^2=0\implies x=\pm\sqrt2$

So the maximum area is obtained when the vertices are the points (-√2, 0), (√2, 0), (√2, 4), and (-√2, 4). This rectangle has base 2√2 and height 4, giving a maximum area of 8√2.
