Step-by-step explanation:
<u>Step 1: Define</u>
2x² - 20x = x² - 19
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract x² on both sides: x² - 20x = -19
- Complete the Square [Addition Property of Equality]: x² - 20x + 100 = -19 + 100
- [Complete the Square] Simplify: (x - 10)² = 81
- [Equality Property] Square root both sides: x - 10 = ±9
- [Addition Property of Equality] Add 10 on both sides: x = 10 ± 9
- Evaluate: x = -1, 19

75-30/15=x
Answer:
Please see the attached file the complete answer.
Step-by-step explanation:
First, you need to find the length of the smaller cubes side. To do this you would need to find the square root of 0.25. then you find the volume with the new found side length of the smaller cube by cubing the new side length and once you have your volume of smaller cube right it down.
Now you need to find the big cube volume by cubing its side length. Once you have found both of these volumes you subtract the smaller cube's volume from the bigger cube's volume to get the difference in size. Hope this helps
