Find each product.<br> 1) (5n - 5)(4n - 4)

Paraphin [41]

Answer:

20n² - 40n + 20

Step-by-step explanation:

(5n - 5)(4n - 4)

= 5n(4n) + 5n(-4) - 5(4n) - 5(-4)

= 20n² - 20n - 20n + 20

= 20n² - 40n + 20

Another way to do this:

(5n - 5)(4n - 4)

= 5(n - 1) * 4(n - 1)

= 20(n - 1)(n - 1)

= 20(n - 1)²

= 20(n² - 2n + 1)

= 20n² - 40n + 20

I The cost CC (in dollars) of making n watches is represented by C=15n+85C=15n+85. How many watches are made when the cost is $3

anyanavicka [17]

C = 15n + 85....when C = 385

385 = 15n + 85
385 - 85 = 15n
300 = 15n
300/15 = n
20 = n <== 20 watches were made

You have an above ground pool that is 20 feet in diameter. One bag of sand does three square feet. How many bags of sand do you

r-ruslan [8.4K]

Answer: Number of sand bags are 105

Step-by-step explanation:

Alright, lets get started.

The diameter of pool is given as : $20 \ \text{feet}$

The radius of pool will be : $r=\frac{20}{2}=10$

So the area of the pool will be:

Area = $\pi r^2$

Area = $\pi *10^2$

Area = $100 \pi$

Area = $314.16$

3 square feet is covered by 1 sand bag, so

314.16 square feet will be covered by : $\frac{314.16}{3}$

So, no of sand bag = $104.7$

Rounding off to nearest number

Number of sand bags are 105 : Answer

Hope it will help :)
