21 its 21 because it is 21
Given: k= midpoint
hk=x+6
hj=4x-6
Remember midpoint cuts the segment hj in equal parts that means hk=kj and hk+kj=hj
hk+hk=hj
2hk=hj
2hk=hj
2 (x+6)=(4x-6)
2x+12=4x-6
2x-2x+12=4x-2x-6
12=2x-6
12+6=2x-6+6
18=2x
18/2=2x/2
9=x
hk=kj=x+6=(9)+6=15
kj=15
Answer:
The greatest common factor of the terms is 1.
Step-by-step explanation:
The terms have no variables in common, and the coefficients have no factors in common. The greatest common factor of the terms is 1.

The discriminant is negative (40² -4(30)(51) = -4520), so any linear factors will be complex.
If the question is actually “danielle ran the first 1/5 of a 6 mile race. how many miles did she run?” then the answer is 1 & 1/2 miles.
