Answer:
6
Step-by-step explanation:
The overbar means the digit repeats indefinitely. The repeating decimal 0.333... is equivalent to 1/3, so this is the simple addition ...
3 2/3 + 2 1/3 = 5 3/3 = 6
_____
<em>Comment on the repeating decimal</em>
1/3 = 0.3333... repeating is one of the first decimal equivalents you learn.
__
If you're into repeating decimals. you may have learned how to convert them to fractions:
x = 0.3333... repeating . . . . . . . give a name to the value
10x = 3.3333... repeating . . . . . multiply by 10^p where p is the number of digits in the repeating pattern
10x - x = 3.3333... - 0.3333... = 3 . . . . . subtract: the repeating portions cancel
9x = 3 . . . . . . . . . .simplify
x = 3/9 = 1/3 . . . . .divide by the x-coefficient; simplify
Answer:
pg. 1
teresa: use difference of 2 squares
rico: 6561 is not a perfect square
pg. 2
i think teresa is right and that 6561 can be broken down
problem 1: (x^4-81)^2=(x^2-9)^4=(x-3)^8
problem 2: a. false b. rico
pg. 3
problem 3: a. -1(3x+5)^2 b. teresa is right because it cant still be a perfect square trinomial while having a negative first term.
problem 4: a. (y+3)^2 b. teresa
pg. 4
problem 5: a. (x^n+y^n)(x^n-y^n) b. teresa
teresa got more right, rico is buying pizza

Answer:
B. 30
Step-by-step explanation:
A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.
A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.
Hope this helps
