Explanation: It seems that the first three shapes in this pattern are increasing by one side as they progress, that means they go 3 sides, 4 sides, 5 sides, etc. If this keeps going until the 6th shape, it would land on 8 sides, which is an octagon.
I hope this helps you :)
Answer:
No, it equals 6x-18. The Parentheses are not needed because there is an addition sign because they both are positive. You just add regularly so 2x+4x=6x and -6-12=-18. The result is 6x-18
Answer:
The predicted number of catfish in the pond is 57.
Step-by-step explanation:
We are given that the average number of catfish in the samples was 5.7. If the total population of fish in the pond is 200, the proportion of catfish in the pond will be 5.7/20 = x/200.
We have to calculate the predicted number of catfish in the pond.
The given proportion to us is;
Cross multiplying both the fractions we get;
So, the predicted number of catfish in the pond is 57.
So I work this out on a sheet of paper and I'm pretty sure I did this right.
