Find the GCF
In this case 6
then just see how many times to multiply 6 to get 12xband 18 then that S it
6(2x+3)
The unknown number is 69.
*If you reverse 69, it would be 96. Thus, increasing its value by 27.
96 - 69 = 27
*The sum of its digits 6 and 9 equals to 15.
Answer:
y = 40 / sqrt(pi)
Step-by-step explanation:
The area is 400
We want to find the diameter
400 = pi r^2
Divide each side by pi
400/ pi = r^2
Take the square root of each side
sqrt(400/ pi) = sqrt(r^2)
20/ sqrt(pi) = r
The diameter is twice the radius
2 r = d
2 * 20/ sqrt(pi) = d
40 / sqrt(pi) =d
y is the diameter so
y = 40 / sqrt(pi)
