Answer:
Try -17/22
Step-by-step explanation:
Multiply the numbers
r-<u>1 • 5/22</u> =-1
Which is just
r- 5/22 =-1
Add 5/22 to both sides of the equation
r- 5/22 + 5/22 = <u>-1 + 5/22 </u>
which equals r= <u>-17/22</u>
Answer:
a1= -7
a2=4 <span>• -7= -28
a3=4 </span><span>• -28= -112
a4=4 </span>• -112= -448<span>
a5=4 </span>• -448= -1792<span>
a6=4 </span><span>• -1792= -7168</span>
Answer:
Octagon
Step-by-step explanation:
Formula for a polygon is :
- a = apothem (distance from center to the midpoint of a side
- P = perimeter (sum length of the sides)
Since a regular octagon has 8 sides, and a regular hexagon has 6, the octagon will have the greater area due to greater perimeter.
