4x^2 - 20xy + 25y^2

(2x-5y)^2

Step-by-step explanation:

4x^2 - 20xy + 25y^2=

(2x) ^2 - 2(2x)(5y)+(5y)^2 =(*)

(2x-5y)^2

(*) A^2 - 2AB+B^2 =(A-B)^2

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
