Two Questions: • A rectangle has integer side lengths. If it has an area of 14x+28, where x is a positive integer, what is the difference between the rectangle’s maximum & minimum possible perimeter?

• The sides of a rectangle are 18 and 24cm. We changed one of its sizes by twice as much as we changed the other side to get a square. What is the side of this square?

i need help with this also :(

Step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
