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>

$= - 18 \sqrt{10}$

PLEASE HELP WILL GET BRAINIEST

NeX [460]

You have a lot of questions here, I can help you with a few of them.

When you simplify the polynomials, you put together all of the terms that have the same degree. That means the variables have the same exponents. The number of terms are the items separated by plus and minus signs.

Here are the answers for the first three:

1) $8x^3+2x^2-3x+9
$

2) $4w^2 + 14w + 17$

3) $-3x^3+9x^2 +3x$

Function p gives the perimeter of an equilateral triangle of side length s. It is represented by the equation p(s)=3x

babunello [35]

Answer:

A) p(s) means that the perimeter of the triangle is 60 units.

B) A value to make the equation true is s = 20

Step-by-step explanation:

In the equation p(s) = 60, 60 represents the perimeter of the equilateral triangle.

To find a value of s that makes the equation p(s) = 60 true, plug in 60 as p(s) and solve for s.

p(s) = 3s

60 = 3s

20 = s

So, s = 20 will make the equation true

Market Basket sells chocolate chip cookies . A-Best cookies are 12 cookies for $6.00. A- Okay cookies sell 20 cookies for $ 8.00

agasfer [191]

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4

Step-by-step explanation:

The unit cost is obtained by dividing the total cost by the quantity

Given

<u>Best Cookies:</u>

Cost = $6.00

Quantity = 12

So the unit price will be:

$Unit\ price\ for\ best\ cookies = \frac{6}{12}\\=0.5\ dollars\ or\ 50\ cents$

<u>Okay Cookies:</u>

Cost = $8.00

Quantity = 20

The unit price is:

$Unit\ price\ of\ okay\ cookies = \frac{8}{20}\\= 0.4 \dollars\ or\ 40\ cents$

The unit price for best cookies is $0.5

The unit price for Okay cookies is $0.4
