Answer:
Hence, the conjecture for the sum of first 20 positive integer is:
20×21=420
Step-by-step explanation:
The table is given as:
2 = 2 =1.2
2+4 = 6 = 2.3
2+4+6 = 12 = 3.4
2+4+6+8 = 20 = 4.5
2+4+6+8+10 = 30 = 5.6
Hence, we see the pattern as:
2+4+6+....+2n= n(n+1)
which is the sum of first n even positive integers.
Hence, we are asked to find the sum of first 20 positive even numbers that is we are asked to find the sum when n=20.
i.e. the sum of:
2+4+6+8+..........+40=20(20+1)
2+4+6+8+........+40=20×21=420.
Hence, the conjecture for the sum of first 20 positive integer is:
20×21=420

How can you verify Euler’s formula for this net of a cube?
Answers
This is for any polyhedron that does not intersect itself. The Euler's formula states that the number of faces plus the number of vertices or corner points less the number of edges is always equal to 2.
Faces + Vertices - Edges = 2
A cube has 6 faces, 8 vertices, and 12 edges.
Euler's formula: 6 + 8 - 12 = 2 ⇒ 14 - 12 = 2 ⇒ 2 = 2

Step-by-step explanation:
for this the Pythagoras equation must be true :
c² = a² + b²
c is the Hypotenuse the dude opposite of the right angle in a right-angled triangle.
as such it had to be the longest side.
so, c = 26
and we get
26² = 24² + 25²
676 = 576 + 625 = 1201
wrong, 1201 is not equal to 676, so, 24, 25, 26 are NOT a pythagorean triplet.

The area of the given trapezoid is 56 sq.units.
What is a trapezoid?
A quadrilateral with at least one pair of parallel sides is called a trapezoid.
Given that, the two bases of a trapezoid are 3 and 11 and the altitude is 8
Area of a trapezoid = (sum of the two bases) / 2 × height
= (3+11) / 2 × 8
= 14 / 2 × 8
= 7 × 8
= 56
Hence, the area of the given trapezoid is 56 sq.units.
