Answer: 9 1/8x
Step-by-step explanation:
Answer: 18 cm
Step-by-step explanation:
We know the circumference formula is C=2πr. Since our circumference is given in terms of π, we can easily figure out what the radius is.
36π=2πr [divide both sides by π to cancel out]
36=2r [divide both sides by 2]
r=18 cm
Answer:
5/2 or 3/2
Step-by-step explanation:
(2x-3)(2x-3)
FOIL it out
4x^2-6x-6x+9
4x^2-12x+9=4x-6
add 12x to each side
4x^2+9=16x-6
add 6
4x^2+15=16x
4x^2-16x+15=0
use quadratic formula
Answer:
The sum of its 30 terms is 38167.5
Step-by-step explanation:
Given:
The First term in the AP is -504
The Sum of its 9 terms is -126
To Find:
The sum of its 30 terms = ?
Solution:
The sum of n terms of an AP:
The sum of 9 terms of an AP:
(-4536) +36d = -126
36 d = -126+4536
36 d= 4410
d = 122.5
The sum of its 30 terms is
