The answer of this problem is A because 3 times 21 is 63 and then you plus 1
which is 64
I think that the median decreases, but not so sure.
Answer:
A: The scale would be x3
B: 4/3
Step-by-step explanation:
Because the only difference between them is size so the basic form of the shape remains, having corresponding sides in proportion.
<h2>Explanation:</h2>
Two triangles are similar if the only difference between them is size. Put another way, the basic form of the shape remains. If this is true, then:
- Corresponding angles are congruent
- Corresponding sides are in proportion
Since you didn't provide any graph, I have attached two similar triangles below. As you can see they are right triangles. As we said, corresponding sides of similar triangles are in proportion, so it is true that:

To solve the problem shown above it is important to know that a binomial is a polynomial that has two terms. When the highest exponent of the binomial is 2, it is a binomial with degree 2, this is also called or know as "quadratic binomial". Therefore, keeping this on mind, you must identify which of the polynomial above has degree 2.
As you can see, the answer is: <span>−6x−1 7x²</span>
