Answer:

x²+10xy+25y²

Step-by-step explanation:

(x+5y)²=(x+5y)(x+5y)=x×x+5y×x+x×5y+5y×5y=x²+5xy+5xy+25y²=x²+10xy+25y²

But it can be much easier

(a+b)²=a²+2ab+b²

$490.50 was the original price of the ski set

To solve- you multiply 327 and 0.2 (20%) which equals 65.4

Then you multiple 327 and 0.3 (30%) which equals 98.1

To find the final original price, you add up 65.4,98.1, and 327

Then to double check your answer, you can take 30% and then 20% of the originally price and subtract them from the original price

I hope my answer was clear enough!

What is the slope of the line that goes through (6,5) and (3,1)?

Solving the slope,
m = (y2 - y1)/(x2 - x1)
m = (1 - 5)/(3 - 6)
m = (-4)/(-3)
m = 4/3

The answer is c.
