Answer:
3x+3y−z−7
Step-by-step explanation:
"Let's simplify step-by-step.
4x+2y−z−(x−y+7)
Distribute the Negative Sign:
=4x+2y−z+−1(x−y+7)
=4x+2y+−z+−1x+−1(−y)+(−1)(7)
=4x+2y+−z+−x+y+−7
Combine Like Terms:
=4x+2y+−z+−x+y+−7
=(4x+−x)+(2y+y)+(−z)+(−7)"(Mathpapa)
Answer:
Step-by-step explanation:
<u>Identity</u>
<u>Simplifying the LHS (Left Hand Side)</u>
- (√24-√k)(√24+√k)
- (√24)² - (√k)²
- 24 - k
<u>Equating to the RHS</u>
- 24 - k = 5
- k = 24 - 5
- <u>k = 19</u>
