Answer:
A. The relationship is approximately linear, since for every inch, the number of seeds that should be planted is approximately 3 seeds per row foot.
Step-by-step explanation:
We are given that,
The table shows the relation between the amount of the seeds and the width of row in inches.
As we see that,
12 = 4 × 3
18 = 6 × 3
20 ≈ 7 × 3
23 ≈ 8 × 3
29 ≈ 10 × 3
So, we get that the relationship is linear.
Thus, option C and D are not correct.
The linear equation corresponding the relation is as shown below.
Hence, the correct option is,
A. The relationship is approximately linear, since for every inch, the number of seeds that should be planted is approximately 3 seeds per row foot.

Answer: Yes, she will have enough trim for all four sides of the square, because the perimeter of the square photo (30.98 inches) is less than 32 inches of trim she has.
Step-by-step explanation:
The formula for calculate the area of a square is:
Where "s" is the lenght of any side of the square.
The formula for calculate the perimeter of a square is:
Where "s" is the lenght of any side of the square.
We know that that the area of the photo is 60 square inches, therefore, we can solve for "s" from the formula and find its value:
Substituting the value of "s" into the formula , we get that the perimeter of the photo is:
Therefore, since Alicia has 32 inches of trim and , we can conclude that she will have enough trim for all four sides of the square.
