Answer:
1240.4 mm²
Step-by-step explanation:
The surface area of a pyramid = Area of the all sides + Area of base
Each side is a triangle.
With a regular pentagonal pyramid, the area of each triangle is
For the 5 triangles,
Substituting given values,
Area of base = 440.4 mm²
Surface area of a pyramid = 800 + 440.4 mm² = 1240.4 mm²
It’s 117, I used a calculator
Answer:
B. All four sides are congruent
Step-by-step explanation:
- To prove a quadrilateral is equal, prove the four sides to be equal
- As the defining feature of a rhombus is that it has 4 equal sides
Answer:
Step-by-step explanation:
We have been given an expression 
. We are asked to factor our given expression.
We will factor out greatest common factor of both terms.
We can see that both terms share a common factor that is 
.
We can rewrite terms of our given expression as:
Factor out :
Therefore factorized from of our given expression would be .

Answer:
-3/5
Step-by-step explanation:
The slope can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
Using the values from the marked points, we have ...
m = (-2 -1)/(2 -(-3)) = -3/5 . . . . it is negative
