Answer:
(x+8) (x-8)
Step-by-step explanation:
Since, both terms are perfect squares, factor using the different square formulas. a^2-b^2=(a+b)(a-b) where a = x and b = 8...

Answer:
7 miles per hour
Step-by-step explanation:
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
Hope this helps :)
Answer:
l=40
Step-by-step explanation:
The area is calculated as
A = wl
1200=30l
1200/30=l
40=l
Answer:
A, (13/3 x 5/13)
Step-by-step explanation:
So first, you should change the mixed numbers into improper fractions. To convert, just multiply the whole number by the denominator and add the numerator. Do that to both fractions and you should get 13/3 ÷ 13/5. Since you need to switch to multiplication, switch the sign and flip that fraction/ That asnwer is 13/3 x 5/13. Hope that helps! :)
Use the cone formula:![V = \pi r^{2} \frac{h}{3}](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cpi%20r%5E%7B2%7D%20%20%5Cfrac%7Bh%7D%7B3%7D%20)
And so:
![Area = \pi * 150^{2} * \frac{240}{3} = 5654866.7 inches^{2}](https://tex.z-dn.net/?f=Area%20%3D%20%20%5Cpi%20%2A%20150%5E%7B2%7D%20%2A%20%20%5Cfrac%7B240%7D%7B3%7D%20%3D%205654866.7%20inches%5E%7B2%7D%20%20)
5654866.7 / 12000 = 471,
So the answer is 471 weeks.
Hope this helps.
