Answer: w^2-22w+19

Step-by-step explanation:

X=7w+4w-6\\Y=w^2-11w+13\\

(7w+4w-6)-(w^2-11w+13)\\7w+4w-6-w^2+11w-13\\(7w+4w+11w)+(-6-13)-w^2\\22w-19-w^2\\-w^2+22w-19

Normally we wouldn't have our square variable be negative, so in order to get rid of that negative sign without changing the equation is by multiplying by -1

-1(-w^2+22w-19)\\=w^2-22w+19

Darin bought a new pair of soccer cleats for $59.99. The sales tax is 6.5%. What is the total cost in dollars that Darin will pa
DaniilM [7]
Hello there! So, we find the total cost in dollars by multiplying the price of the cleats by the percent of tax. However, we first need to add 1 to the tax rate in decimal form. 6.5% is 0.065 in decimal form. Now add 1 to that number to get 1.065. Let's multiply. 59.99 * 1.065 is 63.88935 or 63.89 when rounded to the nearest hundredth. There. Darin will pay a total of $63.89.

Note: When it comes to finding the total price of something with tax, add 1 to the percentage rate in decimal form, and then multiply that number by the price to get the total amount. This will help you out, make things easier, and save time.
