Answer:
The correct answer is 40 cm.
Answer:
Looking at this, slope seems to be 2 for the graph
So, looking at your options, -4 is less than 2, therefore, the answer is
D, with slope -4
2*pi*r = 56.52 ........................................
r = 56.52/2pi ...........................................
r = 56.52/6.28 ........................................
r = 9..............
X is the number:
Therefore, the equation is:
8(x-2)=3(x+3)
8x-16=3x+9
8x-3x=9+16
5x=25
x=25/5
x=5
Answer: the equation is: 8(x-2)=3(x+3), and the number is: 5
