Use the table to identify the values of p and that should be used to factor x2 - 3x - 10 as (x + p)(x + 9).

A. -1 and 10
B. 2 and -5
C. -2 and 5
D. 1 and -10

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: what are the following choices

b, i believe, but not sure.

you would need to also lose 1 point for each of the other outcomes for it to be fair.
