(-10/7) (8/3) is it positive or negative

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

d. you cannot tell because there are no values shown.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

if e is the midpoint of bd, then bd is 14.
