It's an expression that consists of variables and coefficients that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
example:
x2 − 4x + 7
1) L×W 12×12=144
2) 12+12+12+12=48
3) L×W×H 5×5×5= 125
5) B×h/2 12×9=108/2=54
According to the FIFO method, the earliest sweaters are the ones that are sold off first, so if we have 24 remaining, 15 were bought in September (at $45 each) and the last 9 were from June (at $38 each). Then we calculate the total value by:
15($45) + 9($38) = $1,017
The value of the inventory is $1,017.
Answer:
see below
Step-by-step explanation:
14. We can represent 1 as √1 and 2 as √4 and because 1 < 3 < 4, we know that √3 is in between 1 and 2. However, 3 is closer to 4 than it is to 1 so √3 is about 2.
15. Again, 3 is √9 and 4 is √16. 9 < 10 < 16 so √10 is in between 3 and 4, however, since 10 is closer to 9 as it is to 16, we know that √10 is about 3.
16. -4 = -√16 and -5 = -√25, since 16 < 22 < 25, we know that -√22 is in between -4 and -5 but 22 is closer to 25 so the answer is -5.
17. -10 = -√100 and -11 = -√121 so -√120 is in between -10 and -11. Since 120 is closer to 121, the answer is -11.
