X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions
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>
Answer:
Step-by-step explanation:
Reduce the ratio to lowest terms, then multiply numerator and denominator by any same value to get another equivalent.

8 costs 40 so 10 costs | 40 / 8 = ( 5*2=10) So your answer is 50 Dollars.
=12-5=7
=21-12=9
when u look at they have a diffrence of 2 so the answer will have a diffrence of 2 =11
