Match each function with the corresponding function formula when h(x) = 2 – 2x and g(x) = –2x + 2. 1.
k(x) = (2h – 2g)(x)
2.
k(x) = (h – 2g)(x)
3.
k(x) = (h – g)(x)
4.
k(x) = (g – h)(x)
5.
k(x) = (g + h)(x)
6.
k(x) = (2g + h)(x)

the answer is 62.8 cubic units

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:   y=2x-3
