36 centimeters because 18 times 2 is 36, and 108 minus 36 is 72. and you want to divide 72 by two because theres' 2 sides
True. Diameter is a line segment joining two points on a circle and passing through the center of the circle.
Answer:
4x^2+20x+25
Step-by-step explanation:
(2x+5)^2 = (2x+5) (2x+5)
Using the foil method : 2x(2x) = 4x^2
(2x) (5) = 10x
(2x) (5) = 10x
5 (5) = 25
Combine like terms
I would suggest factoring using the grouping method. The answer I got was (2n-1)(n+2)
Answer: 17
21-4=17
4+17=21
21+17=38 and so on..
