If a number is decreased by its square the result is 2/9. find the number
PtichkaEL [24]
Let x be the number.
x-x²=2/9, so 9x-9x²=2 or 9x²-9x+2=0=(3x-2)(3x-1). Therefore x=2/3 or 1/3.
Check: 2/3-4/9=6/9-4/9=2/9 and 1/3-1/9=3/9-1/9=2/9.

2.) A zoo is raising a young elephant. They put him on a special high-protein diet to gain weight rapidly. He gains 6 kilograms
Elena L [17]

<u>Answer:</u>

  • The weight after 20 months is 210 kilos.

<u>Step-by-step explanation:</u>

  • 1 month = 6 kilos
  • => 8 months = 6 x 8 = 48 kilos
  • => x + 48 = 138
  • => x = 90

<u>This means that the starting point is 90 kilos.</u>

  • => 1 month = 6 kilos
  • => 20 months = 6 x 20 kilos
  • => 20 months = 120 kilos
  • => 90 + 120 = weight in 20 months
  • => <u>210 kilos = weight in 20 months</u>

Hence,<u> the weight after 20 months is 210 kilos.</u>

Hoped this helped.
