Answer:27
Step-by-step explanation:first you need 40 x 12 for the area for your gravel
so 480 divided by 18 = about 27
Answer:
L = 5
Step-by-step explanation:
use Pythagorean Theorem:
L² + (5
)² = (10
)²
L² + 25(2) = 100(3)
L² + 50 = 300
L² = 250
L = 
= 
· = 5
Answer:
(a+4)(a-4)=a²-4² ITS LIKE THIS BECAUSE ITS AN IDENTITY,
⇒a²-16
Even when we solve it by the regular method of solving polynomials we get a²-16 as answer as there and thats the proof for the identity.
(a+b)(a-b)=a(a-4)+4(a-4)
⇒a²-4a+4a-16
⇒a²-16[NOTE:-4a+4a=0]
Thus we can see that a²-16 is the answer we get when we try to solve it by regular polynomial solution tooo.
And a²-16 is the polynomial from which we get (a+4)(a-4)
6035 =
6000 + 30 + 5
So I would say 3's value is tenths.
Answer:
A) sum = (180)(20) = 3600°
Step-by-step explanation:
The formula for the sum of interior angles for any polygon is (n-2) x 180° with n being the number of sides the polygon has.
We can just plug in 22 into the equation to get our answer:
(22-2) x 180°
= (20) x 180°
= 3600
