The answer would be A) -17 + 2x because if we regroup it we still receive 2x - 17.

2x - 17 = -17 +2x because using commutative property of addition, changing order and sum remains the same.

In the diagram below, BC is an altitude of ABD. To the nearest whole unit, what is the length of CD?
sergiy2304 [10]
For the answer to the question above, I'll show my solution on how you can solve your problem.
AC² + BC² = AB² 
<span>5² + 12² = AB² </span>
<span>25 + 144 = AB² </span>
<span>169 = AB² </span>
<span>13 = AB </span>

<span>Triangle ABC is proportional to triangle ADB. </span>

<span><u>AC </u>= <u>AB </u></span>
<span>AB    AD </span>

<span><u>5</u> = <u>13 </u></span>
<span>13  AD </span>

<span>5AD = 169 </span>

<span>AD = 169/5 </span>

<span>AD = 33.8 </span>

<span>AD = AC + CD </span>

<span>33.8 = 5 + CD 
</span>So the answer is

<span>CD = 28.8 </span>

Help please 40 points

Part 1:

Step 1:

Find the value of G(16)

Using the equation for g(x) =√x, replace x with 16 and solve:

g(16) = √16 = 4

Step 2:

Now using the answer for g(16) replace x in the equation fir f(x) with 4 and solve:

f(x) = x +2

f(4) = 4+2 = 6

Part 2:

following the same steps as part 1:

f(g(x)) would be replacing x in the equation ofr f(x)with the equation for g(x)

f(g(x)) = √x +2
