Answer:
i don't see anything so i cant help you sorry
Step-by-step explanation:
R= -4
a= -3
using ∑n = a(1-rⁿ)/1-r
∑n:10 = -3(1-(-4)^10)/ 1-(-4)
= -3(1-1,048,576)/1+4
= -3(-1048575)/5
= 3,145,725/ 5
= 629,145
Answer:
1430 m
Step-by-step explanation:
1 km = 1000 m
3000 cm = 30 m
1000 + 400 + 30 = 1430
Step-by-step explanation:
sum of all the angles in a triangle is equal to 180°
82 + 70 + (2x + 4) = 180
152 + 2x + 4 = 180
156 + 2x = 180
2x = 180 - 156
2x = 24
x = 12
300 is the answer
(I hope it is correct)
