The perimeter of a square in which A=169cm square root 2?
sergey [27]
I'm guessing you mean:
A = 169 \sqrt{2}

If not, correct me. 

So, then the perimeter of a square is just 4*A, which in this case would be:
4(169 \sqrt{2}) = 676 \sqrt{2}

And that would be your answer: 676 \sqrt{2} units²

4. Jim and Kirk are playing a card game where they trade chips. At the beginning of the game, Jim has four times as many chips a
s2008m [1.1K]

Answer:

(a) j = 4k

(b) 4k - 18 = 18 + k

(c) Jim initially had 48; Kirk initially had 12

Step-by-step explanation:

Given

j = Jim

k=Krik

Solving (a): An equation for the amount they originally had.

From the question, we understand that j is 4 times as many as k.

Mathematically, this is:

j = 4 * k

j = 4k

Solving (b): Equation after Kirk wins

Initially Kirk had k.

To get the new expression, we add 18 to k.

This gives: 18 + k

In the same vein, Jim's number of chirps will reduce by 18.

Initially, Jim had j chirps (or 4k chirps)

To get the new expression, we subtract 18 from j.

This gives: j - 18

So, the equation is:

j - 18 = 18 +k

Solving (c): Number of chirps they started with.

In (b), we have:

j - 18 = 18 +k

Substitute 4k for j

4k - 18 = 18 + k

Collect Like Terms

4k - k = 18 + 18

3k = 36

Divide both sides by 3

k =12

Substitute 12 for k in j = 4k

j = 4 * 12

j = 48
