Nine workers are hired to seed a field by
hand. each is given a plot which is 7x7
feet in size. what is the total area of the
field?

total area is 441 feet

Step-by-step explanation:

area =L×W

So the area of each plot is 49 feet which you get from 7×7

Since there are 9 works and each is given a 49 feet area of work to seed take 49×9 which equals 441 feet.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
