Since it's a regular pentagon, all it's sides are equal so let's solve for x






now let's find the measure of each side, i.e





perimeter = 5 × side length ( for a regular pentagon )


Answer:
20 is the total perimeter
Step-by-step explanation:
X^2 - y^2 = a
2xy = b
x^2 + y^2 = c
A polynomial identity is an equation that is always true.`1
You can relate x^2 + y^2 with x^2 - y^2 and 2xy in this ways.
1) Step 1:
[x^2 + y^2]^2 = x^4 + 2(xy)^2 + y^4 = c^2
2) Step 2:
[x^2 - y^2] = x^4 - 2(xy)^2 + y^2 = a^2
(2xy)^2 = 4(xy)^2 = b^2
x^4 - 2(xy)^2 + y^2 + (2xy)^2 = x^4 + 2(xy)^2 + y^2
------------------------ ---------- --------------------------
↓ ↓ ↓
a^2 b^2 = c^2
Answer: the identity is
c^2 = a^2 + b^2 equivalent to
(x^2 + y^2)^2 = (x^2 - y^2)^2 + (2xy)^2

<h3>Further Explanation
</h3>
Linear Equation in One Variable is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
Whereas Linear Equation in two Variable is a linear equation that has 2 variables and the exponent is one
Can be stated in the form:
x, y = variable
There are several ways to solve an equation
• Add / Subtract / divide / multiply the same value on both sides
• Combine like terms
• Factoring
• Expanding
Like terms are terms whose variables and their exponents are the same.
You can combine and add terms
The algebraic form of 3x - 5 + 23x - 9 is a Linear Equation in One Variable, can be simplified:
• 1. Combine like terms
(3x + 23x) + (-5 - 9)
• 2. Add like terms:
26x -14
