Answer:
5. 49, (x+7)²
6. 36, (x-6)²
7. 81/4, [x-(9/2)]²
Step-by-step explanation:
5. x² + 2(x)(7) + 7² = (x + 7)²
6. x² - 2(x)(6) + 6² = (x - 6)²
7. x² - 2(x)(9/2) + (9/2)² = (x - 9/2)²
Answer:
=45x√5x
Step-by-step explanation:
The provided expression is: 3√5x×3√25x²
We can simplify 3√25x² because √25x²=5x
3×5x=15x
Combine with the rest of the expression through multiplication.
3√5x×15x
=45x√5x
The expression 3√5x×3√25x² is equivalent to 45x√5x.
The expected simplified answer is 45x√5x
