Answer:

15.36\times (-0.45)=-6.912

Step-by-step explanation:

Given : Expression 15.36\times (-0.45)

To find : What is the solution of the expression ?

Solution :

Expression 15.36\times (-0.45)

When we multiply a positive number by negative number then the result is always negative.

Re-write the expression by removing decimal,

15.36\times (-0.45)=-\frac{1536}{100}\times \frac{45}{100}

15.36\times (-0.45)=-\frac{1536\times 45}{10000}

15.36\times (-0.45)=-\frac{69120}{10000}

15.36\times (-0.45)=-6.912

Therefore, 15.36\times (-0.45)=-6.912

<span>Simplifying 15.36x[-0.45] = 0 Reorder the terms for easier multiplication: 15.36 * -0.45x = 0 Multiply 15.36 * -0.45 -6.912x = 0 Solving -6.912x = 0 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '-6.912'. x = 0 Simplifying x = 0</span>

(-18x^2+12x-2)*(x^3+12x^2+48x+64)
prohojiy [21]
<h2>Answer:</h2>

-18x^5-204x^4-722x^3-600x^2+672x-128

<h2>Explanation:</h2>

( - 18 {x}^{2}  + 12x - 2)

( {x}^{3}  + 12 {x}^{2}  + 48x + 64)

There are multiple ways to solve this for example the foil method or the box method. I prefer to do the box method.

First we are going to set it up

After we set it up we have to solve it so first we are going to multiply

{x}^{3}  \times  - 18 {x}^{2}  =  - 18 {x}^{5}

We have to add the exponent

- 18 {x}^{2}  \times 12 {x}^{2}  =  - 216 {x}^{4}

- 18 {x}^{2}  \times 48x =  - 864 {x}^{3 }  \\  - 18{x}^{2}  \times 64 =  - 1152 {x}^{2}  \\ 12x \times  {x}^{3}  = 12 {x}^{4}  \\ 12x \times 12 {x}^{2}  = 144 {x}^{3}

12x \times 48x = 576 {x}^{2}  \\ 12x \times 64 = 768x

- 2  \times  {x}^{3}  =  - 2 {x}^{3}  \\  - 2 \times 12 {x}^{2}  =  - 24 {x}^{2}  \\  - 2 \times 48x =  - 96x \\  - 2 \times 64 =  - 128

Now we have to add them

-18x^5 stays because there is nothing to add to

Now we add the rest

-216 {x}^{4}  + 12 {x}^{4}  =  - 204 {x}^{4}

- 864 {x}^{3}  + 144 {x}^{3}  +  - 2 {x}^{3}  = -  722 {x}^{3}

768x - 96x = 672x

And -128 stays the same

- 1152 {x}^{2}  + 576 {x}^{2}  - 24 {x}^{2}  =  - 600 {x}^{2}

The answer is

-18x^5-204x^4-722x^3-600x^2+672x-128

Teresa is 25 years old, and she makes $30,000 per year. If Teresa were to die,
REY [17]

Answer:

They would receive $22,500 which is 75% of her income

Step-by-step explanation:

Here, we want to know how much the beneficiaries of a life insurance scheme would receive if their principal die.

From the question, we are told that they have the right to claim 75% of her income

From the question also, we were told that what she earns per annum is $30,000

Now, since they have the right to claim 75%, the amount they can claim out of the said income will be;

75/100 * $30,000 = $22,500

Find the slope of the line through the given points.<br> (-3,-18) and (1,2)
katovenus [111]

Answer:

5

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

5

1

= 5

θ =

arctan( ΔY )

ΔX

= 78.69006752598°

ΔX = 1 – -3 = 4

ΔY = 2 – -18 = 20

Distance (d) = √ΔX2 + ΔY2 = √416 = 20.396078054371

Equation of the line:

y = 5x – 3

When x=0, y = -3

When y=0, x = 0.6
