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:
About $1.82
Step-by-step explanation:
Th answer to the question is 20 mm hope this helps
Range is the difference between the highest & lowest number. to find the range of these numbers, you need to subtract the lowest, 48, from 82, the highest.
your answer is a, 34.
You divide 12/29 and that gives you 0.4137 which equals 41 percent
