11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)
The circumference of a circle has the formula:
C = 2 π r
Now when it is dilated by a factor of 4, this only means
that the radius is also multiplied by a factor of 4, therefore the new
circumference is:
C’ = 2 π (4 r)
C’ = 8 π r
So it also grows 4 times.
Answer:
<span>The circumference will be 4 times greater than the
original.</span>
Step-by-step explanation:
f(x)=2(3^x)+1
f(2)=2×3²+1
=18+1
=19
