It is answer b!!! hope this helps
Hi!
<h3>Expanded form is when we multiply each of the digits by how many 0s they have. </h3>
So 253 is (2 x 100) + (5 x 10) + (3 x 1).
17,000
400
9
(<u>17 x 10,000) + (4 x 100) + (9 x 1)</u>
<h2>The answer is C) (<u>17 x 10,000) + (4 x 100) + (9 x 1)</u> (which equals 17,409)</h2>
Hope this helps! :)

Answer:
k = 5
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
15 - 3k = 10(k - 5)
<u>Step 2: Solve for </u><em><u>k</u></em>
- Distribute 10: 15 - 3k = 10k - 50
- Add 3k to both sides: 15 = 13k - 50
- Add 50 to both sides: 65 = 13k
- Divide 13 on both sides: 5 = k
- Rewrite: k = 5
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: 15 - 3(5) = 10(5 - 5)
- Subtract: 15 - 3(5) = 10(0)
- Multiply: 15 - 15 = 0
- Subtract: 0 = 0
Here we see that 0 does indeed equal 0.
∴ k = 5 is a solution of the equation.
Answer:
158.76 square centimeters
Step-by-step explanation:
The quadrilateral is made up of 2 right triangles if you divide the quadrilateral using line segment BD.
The triangle on the bottom has an area of 11.7*15.6/2, which is 91.26.
The triangle on the top has an area of 7.5*18/2, which is 67.5.
If you add up the area of these 2 triangles, you get 67.5 + 91.26 = 158.76
Therefore, the answer is 158.76 square centimeters.
I hope this helped you.
