(-8,0),(-7,2),(1,1) and (0,-6), how many sides does the figure have

4,because when you join 4 coordinates together, it will become a quadrilateral.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
