Multiply first two values in brackets:

5 x 4 = 20

Multiply the outside values in the brackets:

-x * 5 = -5x

Multiply the inside terms:

-x * 4 = -4x

Multiply the last terms:

-x * -x = x^2

Place all values together:

x^2 - 5x - 4x + 20

Simplify it:

x^2 -9x + 20

What is the 28% tax on a 600,00 cash prize?
konstantin123 [22]
•❋Let's start with the first step: Converting 28% into a decimal. 
To do this you can multiply it by 100 which gives us .28.
Now we have $600.000 in cash and we need to then multiply it by .28.
.28*600=168.
Now we are going to subtract what we just got by the original amount $600.000
(we can also say that it is $600)
So $600-$168=$432
Now we have out answer
28% tax on a $600.000 cash prize = $432

Illusion [34]

Answer:

I believe it's 188

Step-by-step explanation:

If there was a total of 564 and the cheeseburgers was three times the amount, you need to divide 564 by 3. 564 divided by 3 equals to 188. I am pretty sure this could be the correct answer!
