Answer:
I think the error is that the variable x came before the whole number 2.
<u>Answer:</u>
6800 will be the population after 128 years.
<u>Step-by-step explanation:</u>
times it doubles: 128 / 64 = 2 times
so increase in population = 1700 * 2 * 2 = 6800 people.
To find a percent, you need to put the numbers into a fraction first. Since the total number of beads is there, that is the denominator (number on the bottom of the fraction). The purple bead number will go on the top. This makes the fraction 8/12. When you divide 12 by 8, you get the decimal 0.66666667. You move the decimal two places over and get ~66%. This makes your answer B. Hope this helps! :)

That is literaly your code, put the letters in order.
The larger triangle ABC is similar to the smaller triangles as follows.
Triangle ABC ~ triangle DBA by AA similarity because they share angle B and angles A and D are right angles.
Triangle ABC ~ triangle DAC by AA similarity because they share angle C and angles A and D are right angles.
So you can set up the following proportions, seeing that the answers are involving either AC^2 or AB^2.
AB/BD = BC/AB When you cross multiply, you get AB^2 = BC times BD, which is the first answer listed.
Using the other proportion, AC/CD = BC/AC, when you cross multiply, you get AC^2 = BC times CD, which is not one of the answers listed.
