Rationalize the denominator of each of the following 4 by (root7+root3)​
Solnce55 [7]

Answer:

4/(√7 + √3)

Step-by-step explanation:

=> Multiply and divide by (√7-√3)

=> 4(√7 - √3)/((√7 + √3)(√7 - √3)

=> 4(√7 - √3)/((√7)² - (√3)²)

=> 4(√7 - √3)/((7) - (3))

=> 4(√7 - √3)/4

=> √7 - √3

Given that j || k, what is the measure of the missing angle?
anzhelika [568]
60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.

Alex wrote the expanded form for the number 165.038 as 100+60+5+30+8. Was he correct? If not give expanded form.
oksano4ka [1.4K]

We have the next number

165038

The expanded form of the number is

100000+60000+5000+30+8

Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain

\begin{gathered} 100+60+5+30+8=203 \\ \text{And }203\ne165038 \end{gathered}

Finally, the correct answer is

100000+60000+5000+30+8
