Answer: C
Step-by-step explanation:
40/5 =8
20≤8+12
20≤20
18k - 4k = -10 - 4k
18k - 4k + 4k = -10
18k = -10
k= (18/10) = (9/5) = 1.8
Answer:
The greater root of
is x = 3/2.
Step-by-step explanation:
Here, the given equation is : 
Now, solving the given expression by SPLITTING THE MIDDLE TERM,

⇒ Either ( 3x -2) = 0, or (x+4) = 0
⇒Either x = 2/3 , or x = -4
So, the two possible roots of the given equation are, x = 3/2 and x = -4
Now, out of both two possible roots, x 3/2 is the Greater.
Hence, the greater root of
is x = 3/2.
