Answer:

Option A , C and D are correct.

Step-by-step explanation:

Double Facts states that the additions in which a number is added to itself.

then; by definition of double facts

Use Double facts to find the sum of 3 + 2

3 + 2

=3 + (3 - 1)

= 3+ 3 - 1

= 6 - 1

= 5

similarly,

3+2 = (1+2) + 2 = 1 + 2+2 = 1 + 4 = 5

Also;

3 + 2 = 3 + (1+1) = 3 +1+1 = 5

therefore, the double facts that used to find the sum of 3+2 are; 2+2 , 3+3 and 1+ 1.

Answer:

Using double facts we get the sum of [tex]3+2=5[/tex].

Step-by-step explanation:

Given: sum of [tex]3+2[/tex].

As we know that:

Double Facts states that the additions in which a number is added to itself.

Applying the double facts to the sum of [tex]3+2[/tex]:

[tex]3+2=3+(3-1)\\3+2=3+3-1\\3+2=6-1\\3+2=5[/tex]

Similarly we can write [tex]3+2=3+1+1[/tex]

                                     [tex]3+2=5[/tex]

And

[tex]3+2=(1+2)+2\\3+2=1+2+2\\3+2=5[/tex]

Hence, Using double facts we get the sum of [tex]3+2=5[/tex].
