Answer:
The answer to your question is letter C. 7y³ + 7n²y² - 22y²
Step-by-step explanation:
y²(4y + 7n² + 2) - 3y² (-y + 8)
Multiply
4y³ + 7n²y² + 2y² + 3y³ - 24y²
Use the associative property for like terms
(4y³ + 3y³) + (2y² - 24y²) + 7n²y²
Simplify like terms
7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²
Answer:
x=3 and x=5
Step-by-step explanation:
its half of the bottom number
Find a common denominator which is 100 and add and the answer is 69/100!
To calculate the average, we will use the following rule:
average = sum of scores / number of scores
sum of scores = 85+72+89+90 = 336
number of scores = 4
average = 336/4 = 84%
