if we add 18 to both side then it becomes 5x=10x+15 and if we divide by five, x=2x+3
Answer:
D,0,2,-2
Step-by-step explanation:
2x^5-3x^3-20x=0
x(2x^4-3x^2-20)=0
x=0
or 2x^4-3x^2-20=0
put x²=t
2t²-3t-20=0
-20×2=-40
8-5=3
8×-5=-40
2t²-(8-5)t-20=0
2t²-8t+5t-20=0
2t(t-4)+5(t-4)=0
(t-4)(2t+5)=0
t=4
x²=4
x=2,-2
t=-5/2
x²=-5/2
it gives imaginary root. so real rational roots are 0,2,-2
Answer:
The answer is B.
Step-by-step explanation:
Given that each box has 9 pineapples. So if there are 6 boxes, there will be 54 pineapples :
6 × 9 = 54 pineapples
The correct answer to 820/42= 19.52 (rounded answer would be 20). I hope I helped :)
Answer: 990
