Given data is that circles are identical. According to this diameters are identical too.
Diameter of the first circle is 4x and for the second 2x+3.
We can make equality 4x = 2x+3 => 2x=3 => x=3/2
Circumference of each circle is C= 2r pi = 2*(3/2) pi = 3 pi
The correct is fifth answer.
Good luck!
Answer:
First triangle x=9
Second triangle x=20
Step-by-step explanation:
Using Pythagorean theorem
40^2+x=41^2
1600+x^2=1681
-1600 -1600
x^2=81
To find x we do the opposite of powers and find the squared
x=9
Second triangle
21^2+x^2=29^2
441+x^2=841
-441 -441
x^2=400
x=20
Answer:
1 yard = 3 feet
so...
22 yards = 3 (22)
3 x 22 = 66
conversion factor: 3/1
Step-by-step explanation:
Answer: 16b
Step-by-step explanation:
distribute
2a+6b+-2a+10b
combine like terms
2a+6b+-2a+10b
(2a+-2a)+(6b+10b)
16b
First, we are going to want to see if there are any terms we can simplify. By examining the numerators and denominators of our functions, we can see that we can remove a 3 from the denominator of the second function and the numerator of the first function. This would be represented as:
Now, we can multiply the fractions. Remember that to multiply fractions, simply multiply both the numerators over both the denominators, as shown below:
By applying this information, we can solve for the product of the fractions:
Our answer is 
.
