Answer
A- 22 square units
B- 28 square units
C- 18 square units
Step-by-step explanation:
A. You can break it up into 3 different rectangles
(1*2)+(2*4)+(2*6)=22
B. You can first start by finding the area then subtracting the the places where it is not covered.
So the area of the whole square is 6*6=36
Now you can subtract the small squares 2*2=4.
This will be put 2 times as there are two small squares.
So you will subtract 8 square units from 36.
36-8=28
C- You can decompose C into a triangle and a rectangle.
The area of a triangle is 1/2*width*height. When you plug the dimensions in you get 1/2*6*2=6 square units.
Now to find the rectangle. The formula is width*length. Plug the dimensions in and you get 2*6=12 square units.
Just add those two together and you get 18 square units.
Answer:
Option B.
Step-by-step explanation:
It is given that the sides of an equilateral triangle are 8 units long.
Draw an altitude of the triangle.
Altitude of an equilateral triangle is perpendicular bisector.
Let x be the length of the altitude of the triangle.
According to the Pythagoras theorem

Using Pythagoras theorem we get




Taking square root on both sides.


The length of the altitude of the triangle is 4√3 units.
Therefore, the correct option is B.
The degree of the polynomial is 6
<h3>How to determine the
degree of the
polynomial?</h3>
The polynomial is given as:
5yª + y² + y² +y+1
The variable of the above polynomial is y
The highest power of y is 6
This represents the degree of the polynomial.
Hence, the degree of the polynomial is 6
