in the grid below, the vertices of triangle ABC are A(-1,9), B(7,2), and C(-1,2). Which is closest to the area of triangle ABC? ASAP

answer: d. $20

step-by-step explanation:

just took the test

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the answer is the third / last answer

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
