Simplify the following expressions. Put your a<br> (3x³-5x² - 7+ 4x4) + (9x4 - 10x² - 5x³ + 3) =
leonid [27]

first we need to get rid of the ( ) so that we can see what the question really says

(3x³-5x² - 7+ 4x4) + (9x4 - 10x² - 5x³ + 3)

= 3x³-5x²-7+4x⁴+9x⁴-10x²-5x³+3

now all we need to do is add up the numbers with the same x's

<em>3x³</em>-5x²-7<u>+4x⁴+9x⁴</u>-10x²<em>-5x³</em>+3

= 13x⁴-2x³-15x²-4

What is the total price of a $45.79 item when a 7% taxe is added
meriva

Answer:

$42.58

Step-by-step explanation:

You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.

in this case:

45.79x0.07 = 3.205 (rounded 3.21)

45.79-3.21 = 42.58
