A) Factor using the difference of squares formula: a^2 - b^2 = (a+b) (a-b)
a = X and B = 33
(x+33) (x-33)
b)
67^2 - 33^2 =
(67 * 67) - (33 * 33) =
4489 - 1089 = 3400

Answer: 
Step-by-step explanation:
Given
The area of the square is 
Suppose a is the side length of the square
The area of the square is given by
So, we can write
length of each side is
Answer:
The possible lengths of the third side is all real numbers greater than 4 inches and less than 20 inches
Step-by-step explanation:
we know that
<u>The Triangle Inequality Theorem</u>. states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
Let
x -----> the possible lengths of the third side
Applying the Inequality Theorem
1) 12+8 > x
20 > x
Rewrite
x < 20 in
2) 8+x > 12
x> 12-8
x > 4 in
therefore
4 in < x < 20 in
The possible lengths of the third side is all real numbers greater than 4 inches and less than 20 inches
