Mortimer wants to change the shape of his garden. the garden is now 3 feet longer than its wide, but if he increases the length by 4 feet and decreases the width by 1 feet, he will gain 8ft^2 in area. what are the original dimensions of the garden?

The original dimensions of the garden are

Length

Width

Step-by-step explanation:

Let

x-----> the original length of the garden

y-----> the original width of the garden

we know that

-----> equation A

The original area is equal to

substitute equation A

if he increases the length by 4 feet and decreases the width by 1 feet, he will gain 8ft^2 in area

so

The new area is equal to

substitute equation A

Remember that

substitute the values

find the value of x

therefore

The original dimensions of the garden are

Length

Width

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:

original price = p

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%
