Answer: Option C

Step-by-step explanation:

the blue tiles are positive, and the red ones are negative.

The upper ones are a number and the lower ones are other, so the equations that we have are:

upper: x^2 + 4x - 2

lower: x^2 - 2x + 4

so this can be written as:

then we have:

upper + lower = (x^2 + 4x - 2) + (x^2 - 2x + 4) = 2x^2 + 2x + 2

Then the correct option is C, while this is written as:

(x^2 + 4x - 2) - (-x^2 + 2x - 4) = 2x^2 + 2x + 2

Where you can distribute the minus sign with the second parentheses, and get our previous equation.

I would like to purchase 20 products at a cost of $65 per product. What would be my total with 3.5 sales tax
alexandr402 [8]

Answer:

Answer:

The total is: $ 1345.5

Step-by-step explanation:

It is given that:

I would like to purchase 20 products at a cost 65.00 per product.

This means that the cost of 20 products will be:

Also, there is a sales tax of 3.5%

This means that a person has to pay a extra 3.5% on the total cost of the items he purchased.

i.e. he need to pay 3/5% on $ 1300

This means that the amount of tax he need to pay is: 3.5% of 1300

                                                                             =  3.5%×1300

                                                                            = 0.035×1300

                                                                           = $ 45.5.

Hence, the total cost is: $ 1300+$ 45.5

This means that the total cost is: $ 134.5

427 thousand in a scientific notation
ira [324]

Answer:

4.27 x 10^{5}

Step-by-step explanation:

The whole digit cannot go past 10 or be less than 1:

1 - 10 is the numbers of its max.

427,000

We would move the decimal point between 4 and 2 making:

4.2700

(Originally the decimal point moved 5 places because 427,000 is a whole number, which means the decimal point would be considered at the end, as shown below)

427,000<u><em>.</em></u>

By moving 5 places to the left this will be part of your: scientific notation as

___ x 10^{5}

(Then plug in 4.27 in front of your notation)

4.27 x 10^{5}

That is your answer!
