sorry for taking your points

Parentheses first:
So, 12 + 4 x 13 - 2
12 + 52 - 2
64 - 2
62
Irrational roots occurs with its conjugate.
Therefore, -√3 is also root of the function.
The answer is -√3.
0.75 x 14 = 10.50
15 - 10.50 = 4.50
your answer is : Sharon will receive $4.50 change
L being the length, W being the width.
So:
if the Length is 8cm more than twice the width, we have:
2W+8
so it's:
perimeter of a rectange = 2(2W+8)+2W
You asked me not to simplify it, so that should be your answer.
