Answer:
16443
Step-by-step explanation:
a = 7676 - b
b = -8767
then:
a = 7676 - (-8767)
a = 7676 + 8767
a = 16443
Check:
16443 -8767 = 7676
Answer:
DB = 82
Step-by-step explanation:
3x + 8 + 4x + 10 = 8x
7x + 18 = 8x
18 = 8x - 7x
18 = x
----------------------------------------
DB: 4x + 10
4 (18) + 10 = 82
Answer: 6
Step-by-step explanation:
A'B' = AB, and B'C' = BC. So A = (1/2)(3)(4)=6.
R = 12/2 = 6 π = 3.14
Circumference of a circle: C = 2πr
2*3.14*6
6.28*6 = 37.68 or 37.69
The last options seems reasonable
Hope that helps!
