Everything is divisible by five, so pull out five
5(-k^2+4k-6)
Since BD joins the midpoints of two sides of a triangle, it is half the length of the third side, FE.
BD = (1/2)FE = (1/2)(23.5) = 11.75
Answer: B. 11.75
You can use this equation $598.30+X=$954.70
Simplest form of:
12/30=2/5
12/20=3/5
21/35=3/5
