Answer:
-2r+4 or 4-2r (same answer!)
Answer:
Step-by-step explanation:
We will prove the converse of the postulate,
"If a line parallel to one side of a triangle and it intersects other two sides of the triangle, then the line will divide both the sides in the same ratio"
Segment DE intersects AB and BC at D and E respectively,
Ratio of the segments of two sides,
1.5 = 1.5
True.
Therefore, lines AC and DE are parallel.
Itttttttt hits the negative 6 on the line i think
Answer:
The total surface area is
Step-by-step explanation:
we know that
The total surface area of the composite figure is equal to the lateral area of the pyramid plus the lateral area of the cube plus the area of the base of the cube
The lateral area of the pyramid is equal to the area of the four lateral triangular faces of the pyramid
The lateral area of the cube is equal to the area of the four lateral square faces of the cube
so
we have that
substitute
Round to the nearest square centimeters
