A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is <em>x</em>, then the diagonal is such that
√(2) <em>x</em> = 10 cm
→ <em>x</em> = 10/√(2) cm ≈ 7.07 cm
The perimeter of a square is 4 times its side length, so the perimeter is
4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm
which makes 28.4 cm the closest answer.

Step-by-step explanation:
<u><em>Note:</em></u><em> It seems typo in the question. 5% should read 59.</em>
Let 3 credit courses = x, 4 credit courses = y
<u>As per given we have following equations:</u>
<u>Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:</u>
- 4(x + y) - (3x + 4y) = 4(18) - 59
- 4x + 4y - 3x - 4y = 72 - 59
- x = 13
The answer is 13
Correct choice is A
A is correct

♂️ but if you know please answer
Answer:
Concept: Mathematics
When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.
- 1.365 × 10^1
- You see its positive 1 hence we move one space to the right
- Our answer is now 13.65
You keep doing the same thing
- 1.365 × 10^2
- 136.5
Lastly
- 1.365 ×10^3
- 1365
