Answer:
4.
Step-by-step explanation:
A square has four sides of equal length.
And, the formula for area of a square is a^2.
And, 4^2 or 4⋅4 = 16.
Therefore, the side length of the box is 4.
Answer:
a=9 b=18
Step by-step explanation:
First we will find b.
Because there is no 18 in this set and it's an even set of numbers, this would mean that 18 is not present in the set.
The only way for 18 to the be the mean is for b to equal 19. When calculating the average of 17 and 19 your average, or mean, is 18.
a has to be a number ranging from 7-12.
Through trial and error, it can be found that the missing value of a is 9.
Hope this helps!

Answer:
Part A: That 6 pounds of rice costs $18
Part B: (1,3) represents the unit price
Part C: 4 pounds of rice, because $12/3 equals 4
Step-by-step explanation:
Part A: The first point, 6, is on the amount of rice axis and the second point, 18, is on the total cost axis.
Part B: The unit price means the price for just 1 of something, so if you go to 1 pound of rice on the graph, you see it's at 3 on the total cost axis. Which means that 1 pound of rice costs $3.
Part C: From Part B you know that 1 pound of rice equals $3. So if you spend $12, then you can divide that by $3 to see how many pounds of rice you bought. 12/3 equals 4, so you bought 4 pounds of rice. Or you can count by 3's until you get to 12: 3, 6, 9, 12. That's 4 times so that means you bought 4 pounds of rice.
Yes they are right you did a great job!
