Find the greatest common factor of 6a^2b^2c^2d and 2acd^2 a. acd b. 2acd c. 2acd^2 d. 2a^2b^2c^2d^2

2acd

Ironically it is the lowest index which is the Greatest common factor. (You cannot get more from a term than what is there.)

Make sure that a particular base is in both terms and use the lowest power for the GCF.

2acd
There is no b factor in the second term, so it cannot be common.

The opposite happens when find the LOWEST common multiple . then it is the HIGHEST power which has to be used, because the LCM has to contain the whole of each term

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

6e14 is the answer.
