Answer:
I think it would be a obtuse triangle.
Step-by-step explanation:
Considering the Triangle Inequality theorem, for sides to make a triangle to two smallest sides must have a greater sum then the longest. Now that we know its a triangle we must decided what type of triangle it is. You can rule out acute because of the 14. Now, I used the 3:4:5 right triangle rule, which states that a right triangle must a a ratio of 3:4:5. Again, I think the 14 causes the triangle to be obtuse.
If the quadratic is a perfect square, then there has to be a way to write the quadratic as

, where

is a root of the equation. Expanding it out, we see that

Now let's compare this form to the one that we were given. Since

matches up with

,

has to equal either

or

. So, since

in the original equation matches up with

in the equation we found,

and

or
Answer:
A and C
Step-by-step explanation:
By letting x = 0 she is eliminating the terms in x , rather than simplifying
A
9x - 3x - 4 ← collect like terms
= 6x - 4
B
12x - 4 ← already in simplest form
C
5x + x - 4 ← collect like terms
= 6x - 4
Thus A and C are equivalent expressions
