Answer:
-3x²+17x-20
Step-by-step explanation:
When you apply the distributive property (which you did correctly), you simply multiply each number or variable in which you have to distribute it to (which again you wrote correctly) and then you add them all together.
(3x)(-x)=-3x²
+
(3x)(4)=12x
+
(-5)(-x)=5x
+
(-5)(4)=-20
Add those and you will get your answer. Hope this helped :)
Make the picture bigger, can barely see it
A markdown in math is basically a decrease in whatever numbers you are working with.
To find 10% of 82, you do 82*.1 so 8.2 is taken off the total.
So if we do 82-8.2 you get 73.8 as the sale price
Hope this helps
