I think the answer is a I'm not sure
Answer:
The answer to your question is letter D
Step-by-step explanation:
Letter A. It is not possible because it is necessary to considers the variable (number of weeks)and this option does not consider it.
Letter B. It is not possible besides it consider the number of weeks the results do not correspond with the conditions given.
Example: for week 1, the number of freckles is 10 + 2¹ = 10 + 2 = 12, and the number of freckles must be 20.
Letter C. It is incorrect because the numbers of freckles do not correspond with the conditions.
Example: week 2 f = 2(10) ² = 2(100) = 200, it is higher than the expected.
Letter D. This is the correct answer because it satisfied the conditions given.
Answer:
interior angle of a heptagon = 900 degrees
900 = 4x + (3x + 60)
840 = 7x
840/7 = 120
X = 120
120 X 4 = 480
120 X 3 = 360
480 + 360 + 60 = 900
4 angles = 120 degrees each
3 angles = 140 degrees each
The answer to this question is x = 13/9 = 1.444
You are dividing the number with the x so 4 when you divide 4 on both sides 4x cancels out because it’s 0 and 8 divides by 4 is 4 so y=4
