Find the perimeter of the polygon
Zielflug [23.3K]

Answer:

100

Step-by-step explanation:

Okay so I'm not 100% sure but I think it's 100 because:

Angle B and D are the same, so the 12.5 areas will be the same (I honestly suck at explaining I'm really sorry.) But, if you add the sides from angle B and D it will be 50 because 12.5 + 12.5 + 12.5 + 12.5 (or 12.5 * 4). Meanwhile, For angle A and C, both outsides are the same as the other side.

I'm so sorry I can't explain the problem well but once you add them:

11.5 + 11.5 + 12.5 + 12.5 + 12.5 + 12.5 + 13.5 + 13.5 = 100

Hi there!

So first off, here are little definitions you need to know in order to be able to answer your question :

<u>Constant</u> means that the rates of change are the same.

<u>Variable</u> means that the rates of change are different.


But from what I can see, you don't even need those definitions because you got both answers right!


Continue your great work! If there's anything just let me know! :)

Janae and Jerome each have m marbles. Gwen has 4(m + 2) marbles. John has 8m + 4 marbles. If John has more marbles than Janae, J
Ne4ueva [31]

Answer:

C, D, E

Step-by-step explanation:

The numbers of marbles are:

  • Janae - m;
  • Jerome - m;
  • Gwen - 4(m+2);
  • John - 8m+4.

Janae, Jerome, and Gwen combined have

m + m + 4(m+2) = m + m +4m + 8 =6m + 8 marbles.

If John has more marbles than Janae, Jerome, and Gwen combined, then

8m+4>6m+8,\\ \\8m-6m>8-4,\\ \\2m>4,\\ \\m>2.

So, possible answers are

  • Janae and Jerome each have 3 marbles;
  • Janae and Jerome each have 4 marbles;
  • Janae and Jerome each have 5 marbles.
