AE,BF,CG,DH are all parallel to each other. Also EF=FG=GH
Deffense [45]

Answer:

x = 4

BC = 20

Step-by-step explanation:

From what we have, the measures EF = FG = GH

That means;

AB = CD

Thus;

5x = 2x + 12

5x - 2x = 12

3x = 12

x = 12/3

x = 4

BC = AB = CD = 5(4) = 2(4) + 12 = 20

Colin invests £2200 into his bank account. He receives 2.5% per year simple interest. How much will Colin have after 3 years? Gi
Helga [31]

<u>Answer:</u>

  • Colin will have $2365 after 3 years.

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

<u>Using PRT/100, we can find the interest and then sum it up with the principle amount.</u>

  • => 2200 x 2.5 x 3/100 = Interest
  • => 22 x 2.5 x 3 = Interest
  • => 55 x 3 = Interest
  • => 165 = Interest
  • => 2200 + 165 = Total amount
  • => $2365

Hence, <u>Colin will have $2365 after 3 years.</u>

Hoped this helped.
