Answer:
-4,-5/2
Step-by-step explanation:
2x^2+3x-20 =0
2x^2+8x-5x-20 =0
2x(x+4)-5(x+4) =0
(x+4)(2x-5) =0
Either,
x+4=0
x=-4
Or,
2x-5=0
2x=5
x=5/2
Answer: The correct answer is Choice C.
Step-by-step explanation: The drama club raised 150% of their goal, which is represented by choice c.
The proper way to calculate this percentage is to calculate how much they earned over the goal. They earned $150 over a goal of $300, so you divide 150 by 300 to determine the percentage.
150/300 = .5, or 50%
So, they earned 100% (300) plus 50% (150), for a total of 150% of the goal.
