It will be 4:9 as well.
Circumference = 2πr,
r1 : r2 = 4:9 so this means that 2πr1 : 2πr2 = 4:9, because 2π = constant
I’m guessing x would be 30. 30 times 3 would be 90. Also the angles equal a right angle
Answer:
I think it is the first one. I may be wrong.
Step-by-step explanation:
Answer:
5-x
Step-by-step explanation:
you will simplify the eq. it will be (x+8)-(x+8)(x-4)
taking (x+8) as common(1-x+4)
(x+8)(5-x)
Answer:
The graph is a solid line, and the shading is above the line.
Step-by-step explanation:
Given
Required
Describe the graph of the inequality
We have:
Subtract x from both sides
The sign 
implies that the graph has a solid line
The sign which means greater than or greater also implies that the upper region is shaded
