Factor 16 in two different ways

4x4, 2x8

Step-by-step explanation:

Factor means numbers u multiply to give u the required number and can go without any remainder.

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

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
