-1 3 5 8 13 It is because x is grows by the number you put in and you add the 5
Area is t<span>he square units inside a 2D figure</span>
I'm not to clear on what this triangle is trying to say but if 18 is a side and 12 is a side let's use the Pythagorean theorem to solve for the other side
18²=a²+12²
324=a²+144
180=a²
√180 = a
13.41 =a
since x look about twice a
x=2*13.41
x=26.8
<u>ANSWER </u>
The correct answer is option B
<u>EXPLANATION</u>
When we analyse carefully we can see that PQR is mapped on to P'Q'R' by the rule




That is to say the <em>x-coordinates</em> are <em>negated</em>. Hence y-axis is the mirror line.
Since reflection is a rigid motion, the two triangles are congruent. That means the two triangles PQR and P'Q'R' are equal in all respect.
