What is the answer (6√2)(-3√5)

alexgriva [62]

Solution:

$- 18 \sqrt{10}$

<h3>Step-by-step explanation:</h3>

<h3>1. Apply rule : a(-b) = -ab</h3>

$= - 6 \sqrt{2} \: \: • \: \: 3 \sqrt{5}$

2. Apply radical rule : $\sqrt{a} \sqrt{b} = \sqrt{ab}$ , $a \geqslant 0$ , $b$

$= 6 \sqrt{2 \: • \: 5} \: • \: 3$

<h3>3.Multiply the numbers : 2 • 5 = 10</h3>

= $6 \sqrt{10} •3$

<h3>4.Multiply the numbers : - 6 • 3= - 18</h3>

$= - 18 \sqrt{10}$

The length of a rectangular box is 4 times its width, and its height is 7in more than its width. The volume of the box is 126in3

Ierofanga [76]

Answer:

1.88 inches

Step-by-step explanation:

The volume is the product of length, width, and height. If w represents the width of the box, then its length is 4w and its height is w+7. The volume is then ...

V = (4w)(w)(w+7)

We want to find the value of w that makes V=126. It is convenient to use the graphing calculator to look for zeros of a function, so we can write the equation as ...

V - 126 = 0

4w·w·(w+7) -126 = 0

The only positive solution to this equation is near w ≈ 1.883.

The width of the box is about 1.88 inches.
