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)
Answer:
π(12.1)²
Step-by-step explanation:
12.1 is the radius
Formula for base = πr²
= π(12.1)²
Answer: C
Step-by-step explanation:
C becuase they kept the fee so thats +4 so now were looking for x. Last year it was 6 and they doubled it so its 12
Answer:
6 1/4, 6 3/7, 6.5, 6.625
Step-by-step explanation:
6 1/4 is 6.25 so that makes it the smallest and 6 3/7 is still small and everything else is easy
Hello There!
Ethan would pay $31.99 or rounded up two 32 which ever is your answer choice
Thus being why.
if you times 39.99 x .20 you get 7.998
39.99 - 7.998 is 31.99
Hope This Helps!
