For rounding, you look at the number to the right of it.
In this case, it would be 7
because 7 is greater than 5, it is rounded up (remember, 5 and up is round up, while 4 and lower is round down)
So her answer should be 1300

Given:
The figure of a pentagon.
To find:
The value of the x.
Solution:
We know that, the sum of all interior angles of a pentagon is 540 degrees. So,



Subtract both sides by 12.


Divide both sides by 33.


Therefore, the value of the x is 16.
X^2 - 14 = -10
x^2 = -10 + 14
x^2 = 4....take the square root of both sides, eliminating the ^2
x = (+-) sqrt 4
x = 2 and x = -2
