Answer:
3m+2=11
Step-by-step explanation:
Because equation is joined with equal sign
Replace x with -1, and y = 9
Therefore, (x²y)/-7 becomes (-1² · 9)/-7
-1² is just 1, and 1 × 9 is just equal to 9, so your final answer is -9/7.
Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.
<span>To find the previous average sales, add the units sold in the same month in each of the last 4 years: 24 + 30 + 23 + 27 = 104. Then divide the sum by the number of different values, which in this case is 4. 104/4 = 26. Since sales goals are based on the previous average sales, you should expect to sell 26 units next month.</span>
