The answer to this question is 5a^2-6a+20+(-175a+102)over(5a^2+6a-9)
Answer:
the answer is zero property
Answer:
A line parallel has the same slope, so -3
For a 7 sides polygon which is called heptagon or septagon
Interior angles = (7-2)*180/7 = 128.57°
Exterior angle = 180 - 128.57 = 51.43°
Central angle = 360/7 = 51.43°
The statements which are correct:
<span>3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle
</span>
<span>5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57°
</span>
<span>7. The central angle ABCDEFG is the same measure of the exterior angle
</span>
1+2+3= 6 (even)
2+3+4= 9 (odd)
it can be both
