I think that you assumed that:
2k - 1 = k + 2
However we can't do this, because a square has 4 sides whilst a triangle only has 3 sides.
This means that we can say
4(2k - 1) = 3(k + 2)
We multiply by 4 due to 4 sides of the square, and by 3 due to the 4 sides of the triangle.
Lets expand the brackets, and solve it:
4(2k - 1) = 3(k + 2)
8k -4 = 3k + 6
5k -4 = 6 ( subtract both sides by 3x to collect the x values)
5k = 10 (add both sides by 4 to get the x's alone)
k = 2 (divide both sides by 5 to get what just x is)
So k = 2 units
Answer:
Maybe 12…
Step-by-step explanation:
would it be 12? I really don’t know sorry.
If I get it wrong I can just have a question and post it and you can get some points.
The answer is D) 19
each full cup is worth 3 servings so 6 X 3 = 18 + 1 = 19

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 15
Hypotenuse <em>c</em> = 25
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 15² = 25²
- Isolate <em>x</em> term: x² = 25² - 15²
- Exponents: x² = 625 - 225
- Subtract: x² = 400
- Isolate <em>x</em>: x = 20
