Answer:
Below in bold.
Step-by-step explanation:
Ab = ut
Divide both sides by b
A = ut/b.
The other 2 are solved in a similar way:
Kc = 9a
c = 9a/K
Bd = Ca
d = Ca/B.
Subtract 6 from both sides, leaving only 3x on one side and 15 on the other. divide 15 by 3 and get 5 for x. 3(5)+6=21
Answer:
Step-by-step explanation:
eq. of a parabola with vertex at origin and focus (a,0) is
y²=4ax
a=6
so y²=4×6×x
or y²=24 x
