I don’t know the answer sorry
<span>The expression of the square root of 19x must be simplified when x is equal to 28. This is because possible factors of 28 can be seen to be 4 and 7, and 4 is a perfect square. This means it can be pulled outside of the square root when evaluated. The other options include only prime factors that could not be pulled out. (3,5), (3,7), (1,41)
28 simplifies as such:
Sqrt(19*28) = Sqrt(19*4*7) = 2*Sqrt(19*7) = 2*Sqrt(133).</span>
Answer:
-45x^11
Step-by-step explanation:
-5x^6 * 9x^5
Multiply -5x and 9x together:
-45x
Remember when multiplying powers, you add them together, which leaves you with:
-45x^11
The diameter of the circle is needed. But to solve, you would simply multiply the diameter of the circle by pi (3.14).
