To convey as an algebraic expression simply break down the statements and use any variable to represent the number in the sentence.
10 • x^2 = 40x
10x^2 = 40x
10x^2 - 40x = 0
10(x^2 - 4x) = 0
X(x - 4) = 0
X = 0
X - 4 = 0
X = 4.
Here are two possibilities of what the number can be, but because it is a nonzero number, I believe it would be 4.
The answer is 12.37 hope this helps
Answer:
D. Triangle is correct
Step-by-step explanation:
We are given that,
A polygon is rotated to form the blue block patterns,
As, from the figure, we see that,
The polygon being rotated has three sides.
So, the polygon is a triangle.
Thus, a triangle is rotated to form the blue block pattern.
Hence, option D is correct.
