Answer:
GCF is 4ab
And the expression will be: 4ab ( 3a^2+2ab-5b^2)
Step-by-step explanation:
Factor the GCF :
12a^3b + 8a^2b^2-20 ab^3
We need to find the common terms that are common in each of the term given above
12,8 and 2 are all divisible by 4
a is common in all terms and b is also common in all terms,
So, GCF is 4ab
Taking 4ab common
12a^3b + 8a^2b^2-20 ab^3=4ab ( 3a^2+2ab-5b^2)
Answer:
Option C is correct
a + 0 = a
Step-by-step explanation:
Additive identity:
For any real number x,

We have to find an example of the additive identity from the given options.
Option A.
a+(-a) = 0
Which does not follow the additive identity.
Option B.
a+0 = 0
which does not follow the additive identity.
Option C.
a+0 = a
this equation follows the additive identity.
Therefore,an example of the additive identity is, a + 0 = a
Answer:
? = 56.
Step-by-step explanation:
In the problem, the side 20 corresponds to side 32 and side 20 + 35 corresponds to side 32 + ?.



? + 32 = 8 * 11
? + 32 = 88
? = 56.
Hope this helps!
