Answer:

DF = 14

Step-by-step explanation:

Andrew was wrong in the assumption that DE = EF

Segments of tangents to a circle from the same external point are congruent

That is

EF = FG = 8

Then

DF = DE + EF = 6 + 8 = 14

HELP PLS BRAINLIEST IF POSSIBBLE factor each polynomial completely a^2-ab-8a+8a brainly

sineoko [7]

Answer:

a(a - b)

Step-by-step explanation:

given polynomial: a²- ab - 8a + 8a

We can first simplify this answer by removing like terms,

- 8a + 8a = 0

so we have a²- ab in. the simplest form

we can take this one step further and factor out the a (not simplest form)

a time a = a²

a times b = ab

hence, a(a - b)
