Answer:
D) -4, 0
Step-by-step explanation:
find common difference.
the common difference appears to be +4 as you must add 4 to -12 to get to -8
now we find the missing terms.
the previous term of the first missing term is -8
if the common difference is +4 then the next term would be -8 + 4 = -4
the term after that would be -4 + 4 = 0
the two missing terms are -4 and 0
So since they are similar
AC/BC=CD/CE
so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units
