Rewrite each of the following statements using the other conditional forms: (a) If an integer is a multiple of 4, then it is even. (b) The fact that a polygon is a square is a sufficient condition that it is a rectangle. (c) If x = 5, then x 2 = 25. (d) If x 2 − 5x + 6 = 0, then x = 2 or x = 3. (e) x 2 = y 2 is a necessary condition for x = y.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

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
