Drag the labels to the correct locations on the expanded binomial.
Tom [10]

The expanded binomial is 2x^3+3y^2=7                                                                                              

<u>Step-by-step explanation</u>:

  • The binomial is not shown in correct expansion. It is written in the wrong format. There is a general format for the binomial expansion.
  • The first term should have the highest power. So 2x power 3 will come first. The second term will have power lesser than the first term.
  • So in the second term, 3y^2 will be placed. After that, the equal to = operator will be placed. Finally, the value of the expression will be placed.
  • So the expanded correct form is 2x^3+3y^2=7

HELP PLEASE!
Eduardwww [97]

Answer:

3600 tickets were sold for the musical performance.

Step-by-step explanation:

Given that:

Number of people seated for musical performance = 108

Percent to people to arrive yet = 97%

It means that the people who have already come are 3%.

Let,

x be the number of tickets sold.

3% of x = 108

\frac{3}{100}x=108\\

0.03x = 108

Dividing both sides by 0.03

\frac{0.03x}{0.03}=\frac{108}{0.03}\\x=3600

Hence,

3600 tickets were sold for the musical performance.
