6x+3+5x+1=180
x=16
(5*16)+1=81
1=81
Answer:
C =28.26m
Step-by-step explanation:
We are walking around a circle, which means we are finding the perimeter. The perimeter of a circle is called the circumference.
We find the circumference by
C = pi *d where d is the diameter
C = 3.14 * 9
C =28.26m
A: (-3,-1)
B: (4,-5)
C: (-2,3)
D: (1,4)
Answer:
D. 6
Step-by-step explanation:
Suppose the triangles are similar:
The side lenghts would be proportional as follows
XZ/DF = XY/DE
12/8 = 9/x cross multiply expressions
12x = 72 divide both sides by 12
x = 6
I think it's 108. But I'm not really good at math so...
