Plz help me with dis its one question
tatiyna

Answer:

Alix does. See below.

Step-by-step explanation:

Givens

<em><u>Jenny</u></em>

  • b1 = 90 cm
  • b2 = 80 cm
  • height = 23 cm

<em><u>Alex</u></em>

  • b1 = 90 cm
  • b2 = 70 cm
  • height = 27 cm

Formula

For both territories the answer is based on the formula

  • Area = (b1 + b2)*h/2

Solution

<em><u>Jenny</u></em>

  • Area = (90 + 80)23/2
  • Area = 170 * 23 / 2
  • Area = 85 * 23
  • Area = 1955 units.

<em><u>Alex</u></em>

  • Area = (70 + 90)*27/2
  • Area = 160*27 / 2
  • Area = 80* 27
  • Area = 2160

If you triple 4 and subtract to each day how many days until you have zero
Mrrafil [7]
Do you mean subtract two each day? If so...
4x3=12 and 12 divided by 2 is 6 so it would take six days to reach zero
or
you could manually subtract two from 6 each days as in 12-2=10 (1 day), 10-2=8 (2 days), and so on...
