what is the gcf of 8 and 32?
2
4
8
32
what is the lcm of 20 and 40?
5
10
20
40

gcf = 8  lcm= 5

gcf means greatest common facter.  8 goes into 8 1 time and 32 4 times. therefor 8 is the gcf.  lcm means least common multiple. and 5 is the lowest number that goes into 20 and 40

For the first question, the right answer is 8.

for the second question, the right answer is 40

Step-by-step explanation:

First of all, we need to find the GCF of 8 and 32, for that we need to find the factors of 8 and 32

Factors of 8 are:

8=1, 2, 4, 8.

Factors of 32 are=

32= 1, 2, 4, 8, 16, 32

we can see that 1, 2, 4 and 8 are factors for the two numbers, but 8 is the greatest of these numbers, so the greatest common factor for 8 and 40 is 8.

Now we just need to find the LCM of 20 and 40 we need to find their multiples

Multiples of 20=

20: 20, 40, 60, 80, 100, 120

Multiples of 40=

40: 40,80, 120, 160, 200

We can see that 40, 80 and 120 are common multiples but the lowest one is the LCM

So the LCM of 20 and 40 is 40

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
