8 ___ 22 ____ 19 ________3____9
9 ___ 15 ____ 20 ________5___ 25
10 __ 21 _____19 ________ 2 ___ 4
Mean squared error :
(4 + 4 + 0 + 9 + 25 + 4) / 6
= 46 / 6
= 7.666
= 7.67

Step-by-step explanation:
We can get area of square by doing 2*2
4
We can add the two triangles together and form a square. To find area, we can do the same as above. 2*2=4
We add both together
4+4
8
The degree of the polynomial, 8y give. and the it is a monomial.
<h3>What is a Polynomial?</h3>
A polynomial is an algebraic expression which may be of varying degrees or number of terms.
According to the question;
- The expression given is; 8y.
Since, the highest degree of the variable, y is one; we can conclude that the polynomial is of degree one.
Additionally, since there's only one term in the polynomial, we can conclude it is a monomial.

Explanation:
Let point G be the center of both the hexagon and the circle.
The measure of arc AB is the same as central angle AGB, both of which are 360/6 = 60 degrees. This applies to the other arc measures as well. The full 360 degree circle is split up into 6 equal pieces, each piece being 60 degrees.
