<h2>
Thus, the required "option 4)" is correct.</h2>
Step-by-step explanation:
We find,

To find, the binomial expansion of of
= ?
We know that,

∴ 
Here, n = 7, x = x and y = 2y
= 


∴ The binomial expansion of of

Thus, the required "option 4)" is correct.
Answer:
- Tables A and B represent linear relationship
-------------------------
<h3>Table A</h3>
- x = 2, 3, 4, 5 Difference is 1
- y = 14, 21, 28, 35 Difference is 7
- This is linear and the slope is 7
<h3>Table B</h3>
- x = -2, -1, 0, 1 Difference is 1
- y = 10, 5, 0, -5 Difference is - 5
- This is linear and the slope is - 5
<h3>Table C</h3>
- x = 2, 3, 4, 5 Difference is 1
- y = 48, 72, 90, 114 Difference is inconsistent
Answer:
7
Step-by-step explanation:
Terms are the numbers and/or variables within an equation. For example you have 5 terms in that equation:

The first term is: 
The second term is: 
The third term is: 
The fourth term is: 
The fifth term is: 
Coefficients are the numbers in front of variables (this includes negative/subtraction signs). For example you have 5 coefficients in this equation:
The first coefficient is: 3
The second coefficient is: 7
The third coefficient is: 2
The fourth coefficient is: 9
The fifth coefficient is: -5
Answer How many liters of a 20% acid solution should be mixed with 30 liters of 50% acid solution in order to obtain a 40% solution. ... x=15 liters 15*(.20 pure acid)=3 liters 30*(.50 pure acid)=15 liters That is 18 liters pure acid That is 45 liters solution *0.45 pure acid=18 liters.
