Your formula for this is
and
. Get everything on one side of the equals sign, set it equal to 0 and factor. When you do this you get (x-3)(x+27). The Zero Product Property rule tells us that either x-3 = 0 or x+27 = 0 and that x = 3 and -27. The only thing in math that will NEVER be negative besides time is distance/length, therefore, x cannot be 27 and has to be 3.
The answer to your question is 3
2 ( 3x + 8 ) = 70
6x + 16 = 70
-16. -16
6x = 54
54/6 = 9
x=9
Answer:
k= 1/2
Step-by-step explanation:
2= 5k - k
2= 4k
2/4=k
simplified: k= 1/2
check:
(1/2) +2 = 5*(1/2)
2.5 = 2.5 ✔️
