Answer:
sgsrgrsdg
Step-by-step explanation:
4 (z - 2) + 2 (z -1)
(4)^(z)+(4)(-2)+(2)^(z)
= 4z+-8+2z+-2
= -4z+-8+2z+-2
=(4z+2z)+(-8+-2)
= 6z+-10
Answer:
45 sides
Step-by-step explanation:
If each of the interior angles is 172 degrees, then each of the exterior angles is 8 degrees. Since the sum of the exterior angles of any polygon is 360 degrees, there are 360 / 8 = 45 exterior angles and 45 sides.
Answer:
(a, a+b).
Step-by-step explanation:
Midpoint = [(a+2b + a-2b)/2 ], [b-a + 3a+b]/2
= (2a/2, (2a+2b)/2
= (a, a+b).
