To write the coefficients of the 8 terms, either start with a combination of 7 things taken 0 at a time and continue to 7 things taken 7 at a time or use the 7th row of Pascal’s triangle.
For the first term, write x to the 7th power and 3 to the 0 power. Then decrease the power on x and increase the power on y until you reach x to the 0 and y to the 7.
Simplify by evaluating the coefficients and powers of 3.
444.25(8) = 3554
4000 - 3554 = 446 <== what she still owes
The average of 3 numbers is their total divided by 3.
(150 +205 +178)/3 ≈ 178.67
Rounded to the nearest dollar, the average charge for the period is $178 per month.
1/9 people voted for kiwi. So, 1/9 needs to be transformed into a decimal. 1/9 is equivalent to 0.111... a repeating decimal. Since 0.111.. is not a whole # or an integer, it is a rational number. If you are having trouble understanding rational numbers, check out the following link:

Answer:
The value of x is 3
Step-by-step explanation:
First, you must expand everything:
2(2x+1) - 3(x-1) = 8
2(2x)+2(1) - 3(x)+3(1) = 8
4x + 2 - 3x + 3 = 8
x + 5 = 8
Then, move all the unknown value to one side:
x = 8 - 5
= 3
