Answer:
x = 4
Step-by-step explanation:
The quadrilateral is a rectangle and opposite sides are congruent, hence
10 + 2x = 18 ( subtract 10 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Anser is B). Subtract smallest number

Answer:
(x - 2)(x + 2)
Step-by-step explanation:
If this is a difference of squares, it factors like this.
(x - 2)(x + 2)
The general rule is x^2 - a^2 factors into sqrt(x^2) +/- sqrt(a^2)
That always produces 2 factors: (x + a)(x - a)
