The greatest common factor−5k2 20k − 30 is 
<h3>What is meant by the greatest common factor?</h3>
- The most common factor in mathematics is the highest number that may divide evenly into two other numbers.
- The largest factor that splits both numbers is the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. We multiply them to obtain the GCF. Therefore the GCF for 18 and 24 is 2 * 3 = 6.
- The biggest positive integer that divides evenly into all the numbers with no remainder is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.

Explanation:
BC = 78 is parallel to the midsegment DE.
This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39
-------
DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.
-------
BE = 34 for two reasons
- Quadrilateral EBFD is a parallelogram with opposite sides BE and DF that are congruent.
- E is the midpoint of AB, so BE is half as long as AB
--------
We don't use the info that AC = 48.
Answer:
population=12780
Step-by-step explanation:
7% of 9000 is 630
630 times 6 is 3780
9000 plus 3780 is 12780
tell me is u need me to explain why I did things :)
2/3 x * x = 864
(2/3) x^2 = 864
x^2 = 864 * (3/2) = 1296
x = + sqrt 1296 = 36
length is 36 feet
