Answer:
(x - 4)×(x + 4)
Step-by-step explanation:
(x - 4)×(x + 4) = x^2 - 16
First we need to multiply inside the parenthesis one by one
Multiply x with (x + 4) and the result will be x^2 + 4x
Then multiply -4 with (x + 4) and result will be -4x - 16 we then add both of the result together by adding like terms
x^2 + 4x - 4x - 16 = x^2 - 16 (-4x eliminated 4x) therefore the answer to factorised form of x^2 - 16 is (x - 4)×(x + 4)

Answer:
30/11
Step-by-step explanation:
Let's say x = 2.7272727272... If we multiply both sides by 100, we get:
100x = 272.7272727272...
We now have the equations:
100x = 272.7272727272...
x = 2.7272727272...
Let's subtract the second from the first. Doing so results in 99x on the left. On the right, the entire repeating part (72727272...) cancels out and we're just left with 272 - 2 = 270:
99x = 270
Divide by 99 on both sides:
x = 270 / 99
Simplify:
x = 30 / 11
The answer is 30/11.
Answer:99.9 would be the answer
