Answer:
C. Yes Devon should have evaluated f(3).
Step-by-step explanation:
She substituted the wrong value. For x - 3 to be a factor f(3) must equal 0.
f(3) = 3^3 + 3^2 - 10(3) + 8 = 27 + 9 - 30 + 8
= 14, so x- 3 is not a factor anyway but she did substitute the wrong value.

Every two triangles are similar. Therefore the sides of triangles are in proportion.
We have the equations:
1.
<em>cross multiply</em>
<em>divide both sides by 5</em>
<em>subtract 3 from both sides</em>
--------------------------------------
2.
<em>cross multiply</em>
<em>divide both sides by 3</em>
------------------------------------------
3.
<em>cross multiply</em>
<em>divide both sides by 5</em>
<em>subtract 12 from both sides</em>
----------------------------------------------
4.
<em>cross multiply</em>
<em>divide both sides by 3</em>
