If you're completing the square the answer is in the image.
expression
x^2 + 5x - 5=ax^2+bx+c
a=1, b=5, c=-5, and you can solve it that way.
The polygon would have 18 sides. Hope this helps!
Answer: well your answer is 18360
Step-by-step explanation: so let's say 51,000 is 100% and x is what where looking for, we know x is 36% so write x=36% the you have 51,000=100% now you have two simple equations.
<em>p = 21</em>
Step-by-step explanation:
When you have a midsegment, the base is going to be two times as large as the midsegment. You can find the midsegment if you multiply it by two and set it equal to the base. I have attached a photo below that may help you.
This is the equation we will be using.

Now let's solve! Let's start by distributing the 2 by what's in the parentheses.

Subtract p from both sides.

Add 26 to both sides.
<u>p = 21</u>
Answer:
23 inches wider
Step-by-step explanation:
Subtract the 2 from the width 25 to get 23
