Using the Pythagorean theorem:
12^2 + x^2 = 15^2
144 + x^2 = 225
x^2 = 225 - 144
x^2 = 81
x = sqrt(81)
x = 9
Answer:
(x+7)
Step-by-step explanation:
(x+7)(2x+1)=2x^2+14x+x+7=2x^2+15x+7
The answer is D because the square root of 484 is 22.
<h2><u>
Transversal Line</u></h2>
A transversal line is a line that crosses through two lines on the same plane.
Example:
I attached a photo below showing the Transversal line (the line in red) crossing two lines located on the same plane. <em>Note: The Transversal line is only the red line, not the whole diagram below.</em>
<em>I am open to corrections if I unintentionally added false information :).</em>
