<em>Correct expression: </em>
Answer:
x = 4
x = -4
x = 7i or 
x = -7i or 
Step-by-step explanation:
We do factorization of x^2 - 16
(x^2-16) = (x+4)(x-4)
(x+4)(x-4)(x^2+49) = 0
We require that any term in the multiplication to be zero to fulfil the requirement
so:
if x + 4 = 0 then (x+4)(x-4)(x^2+49) = 0
x = -4
if x - 4 = 0 then (x+4)(x-4)(x^2+49) = 0
x = 4
if (x^2+49) = 0 then (x+4)(x-4)(x^2+49) = 0
x^2 = -49
we have two roots:
If your course has already worked with complex number and the root of -1 then:
7i and -7i are solution as well
because 7i will be: 
and the same reasoning for -7i:

Hi there! To round 10.95 to the nearest tenth, we find the number in the tenth place, which is 9 and look one place to the right. Round up if the number is greater than 5 or equal to 5 and round down if its less than 5.
The answer is 11.0 or just 11.
<em>Ed: Explanation below.</em>

11.00
10.99
10.98
10.97
10.96
10.95 Look at the 9. Then look to the right. Do I round up or down?
10.94
10.93
10.92
10.91
10.90
If the number is greater or equal to 5, you round up. If the number is smaller than 5, you round down. 9 is greater than 5, so we round up.
Therefore, the answer is 11.
