Answer:
15 %
Step-by-step explanation:
42 = members of team A
60 = members of team B
Let x = percent of members transferred
0.01x × 60 = 0.6x = no of members transferred
60 - 0.6x = 42 + 0.6x
60 = 42 + 1.2x
18 = 1.2x
x = 15
15 % of the members on Team B must be transferred to Team A.
Check:
60 - 0.6 × 15 = 42 + 0.6 × 15
60 - 9 = 42 + 9
51 = 51
OK.
Answer:

Step-by-step explanation:
3x^2 + 5x - 12
To solve it, you need an equation, so I think you mean this equation.
3x^2 + 5x - 12 = 0
Using the quadratic formula, you have a = 3, b = 5, c = -12.
