Leah claims that these figures are not similar. When she compared the heights, she wrote 27. Then she compared the bases and got
1 answer:
Answer:
<h2>Leah is actually wrong, because those rectangles are similar.</h2>Step-by-step explanation:
Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.
In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.
As you can observe, both ratios are equal.
Therefore, those rectangles are congruent.

Answer:
Step-by-step explanation:
we know that
In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, called the common difference
The formula for an Arithmetic Sequence is equal to
where
d is the common difference
n is the number of terms
a_1 is the first term of the sequence
In this problem we have
substitute
so
<u><em>Find the first ten terms</em></u>
For n=2 ---->
For n=3 ---->
For n=4 ---->
For n=5 ---->
For n=6 ---->
For n=7 ---->
For n=8 ---->
For n=9 ---->
For n=10 ---->
The sequence is
