Find the value of ​f(4​) for the function.
​f(a)=3​(a+2​)−2

f(a)=3(a+2)-2

f(4)=3(4+2)-2

f(4)=3(6)-2

f(4)=18-2

f(4)=16

Hope  this helps!

f(4)= 16

Step-by-step explanation:

f(4)= 3(a + 2) -2

f(4)= 3(4 + 2) -2

f(4) = 3(4) + 3(2) -2

f(4)= 12 + 6 -2

f(4)= 18-2

f(4)= 16

me! what did you put for this question?

step-by-step explanation:

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
