A square has four even sides and the perimeter is equal to the sum of all of the sides.
$P=s+s+s+s=4s$
So we can evaluate the equation for P and then solve for s.
$78.4=4s \\ \frac{78.4}{4} =s \\ s=19.6in$

Answer:

The length side of the original square banner was 9 ft

Step-by-step explanation:

Let

x-----> the length side of the original square banner

we know that

The new area of the banner is equal to

$91=(x+4)(x-2)$

Solve for x

$91=(x+4)(x-2)\\ \\91=x^{2}-2x+4x-8\\ \\x^{2}+2x-99=0$

Solve the quadratic equation by graphing

The solution is x=9 ft

What is 3 + -5= and is it a positive or negative number and how?

Natalka [10]

It is -2. This is negative. For instance, if you had 3 candies and your mother took away 5, you would not only have 0 candies, but you would owe your mother 2. This is expressed as a negative number. Please mark Brainliest!!!
