Answer:
B
Step-by-step explanation:
because it is (5,15) and B is (5,15)
We can mark "breadth" as x so lenght will be x +4 so x+x+x+2+x+2 =11
Therefore 4x+4=11
4x=7
X=7/4
So length is x+4 =7/4 +4
Answer: The volume of shell is 12.8π mm².
Step-by-step explanation:
Since we have given that
Radius to the inside of the shell = 4 milimeters
Radius to the outside of the shell = 4.2 milimeters
Since r changes from 4 mm to 4.2 mm
so, 
As we know that
Volume of shell is given by
So, the volume of shell is 12.8π mm².
Answer:
3.7
Step-by-step explanation:
≈
Answer:
If you call the smaller integer "x" and the greater integer "y", then:
x+y=3x-11 The sum of the two is 11 less than 3 times the smaller
y=x+1 Because they are consecutive, the greater must be 1 more than the smaller
Then you can solve for x:
x+(x+1)=3x-11 Substitute x+1 for y
2x+1=3x-11 Combine like terms
2x+12=3x Add 11 to both sides
12=x Subtract 2x from both sides
The smaller integer is 12, thus the greater integer is 1 more or 13.
Check:
12+13=3(12)-11
25=36-11
25=25 Yes, so the integers are 12 and 13
Step-by-step explanation:
thats pretty much it
