Answer:
No
Step-by-step explanation:
In a geometric sequence there is a common ratio. The common ratio is the number that when multiplied by a number in the sequence gives you the next number. To find the common ratio, you divide any number by the previous number. Every division must give you the same answer, the common ratio.
Now try to find the common ratio of this sequence.
36/12 = 3
12/3 = 4
The ratios between terms are not equal. There is no common ratio.
Therefore, this sequence is not a geometric sequence.
Using the shortcut for binomial expansion, which still took 45 minutes, I got 23-26. The coefficient on the x^6 term is 34,020; the coefficient on the x^4 term is -495; on the x^7 term it's 1800; on the x^3 term it's 337,920. I'm pooped. The rest is factorial notation, kinda the same thing, but...
Step 1
In the example why is the area of one triangle multiplied by 2.
This is because the hexagon is divided into one rectangle and 2 congruent triangles. Therefore, the area of the two triangles will be the same since they are congruent triangles. In order to get the area of the hexagon, the area of one of the triangles is mutiplied by 2 and added to the area of the rectangle.
Step 2
Find the dimension of one of the shaded triangle from Bev's pattern.
The dimensions will therefore be;
What can you say about the shaded area of all the shaded triangles in Bev's pattern.
The area of all shaded triangles in Bev's pattern are equal. This is because all the shaded triangles have the same dimensions and can be said to be congruent. Hence, they will have the same area.

Step-by-step explanation:
c=a2+b2=82+72
10mm = 47mm
1cm = 10mm
47mm=4.7cm
Hope this helps.
