Consider a pattern that begins with 9 and each consecutive number is twice the previous term. what are the first four terms of this pattern? a. 9, 11, 13, 15 b. 9, 18, 27, 36 c. 9, 27, 81,243 d. 9, 18, 36, 72

"Twice the previous term" means the previous term is multiplied by 2 to get the present term. In other words, the next term is 2 times the present term.

The first term is 9 (given).

The second term is 2×9 = 18.

The third term is 2×18 = 36.

You can figure the 4th term, but there is no need. This is sufficient to identify the correct answer as ...

... D. 9, 18, 36, 72

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
