Answer:
(t + 6)(t - 6)
Step-by-step explanation:
(t - 6)(t + 6)
(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)
= t² - 6t + 6t - 36
= t² - 36
so,
t² - 36 = (t + 6)(t - 6)
Answer:
9 scarves.
Step-by-step explanation:
We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.
We know that equation of two inversely proportional quantities in in form 
, where, k is constant of variation and y is inversely proportional to x.
Let us find constant of variation using our given information.
Now, we will substitute 
in our equation to solve for N.
Therefore, Ariana can make 9 scarves.
The distance traveled by Mr.Nersin = 4 miles
The time for which Mr.Nersin rode first = 1/2 hour
The time for which Mr.Nersin rode after a short rest = 1/10 hour
Then
The total time for which Mr.Nersin rode = (1/2) + (1/10) hour
= (5 + 1)/10 hour
= 6/10 hour
= 3/5 hour
So
Average speed of Mr. Nersin = Distance traveled / Time taken
= 4/(3/5) miles/hour
= (4 * 5)/3 miles/hour
= 20/3 miles/hour
= 6 2/3 miles/hour
= 6.67 miles per hour
So the average speed at which Mr.Nersin traveled is 6 2/3 or 6.67 miles per hour.
Answer:
p = 633.09 ft
Step-by-step explanation:
The distances of each leg are indicated
Add them to get the perimeter
p = 100 + 89.44 + 186.81 + 120.83 + 136.01
p = 633.09 ft
