It could be a square, but it doesn't have to be. A square is a rhombus
with special angles.

C.30
Step-by-step explanation:
Its a pattern that increases by $5 as it goes down.
Answer:
x² + 10x + 25
Explanation:
Before we begin, remember the following:
(a + b)(a + b) = (a + b)² = a² + 2ab + b²
Now, for the given we have:
(x + 5)(x + 5)
We can note that the two brackets are identical.
Therefore, we can apply the above rule as follows:
(x + 5)(x + 5) = (x + 5)²
= (x)² + 2(x)(5) + (5)²
= x² + 10x + 25
Hope this helps :)
It’s um um.......y......e......a.......h. Yeah
