NEED HELP ASAP WILL GIVE BRAINLIEST REAL ANSWERS PLZ

Step-by-step explanation:

Choice A

Log 10 = 1.

So A is actually right, although it does not look it.

log(20 * x^5 ) - 1   is correct.

Choice B

Log(x^5 * 20 / 10)

log(2 x^5)  

Choice B is also correct

Choice C is not correct, or if it is, I don't know how to get it. You need the 20 in there somewhere.

No! Dis not correct. The 2 is not raised to the 5th power.

And E is not correct.  I'm not sure how they got it. Even + 1 is not correct. It should be -1 if that is how it is to be done.

step-by-step explanation:

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°
