Answer:
greater than 2
less than 28
Step-by-step explanation:
The sum of the lengths of the two shortest sides must be more than the length of the longest side. If x is the shortest side, ...
... x + 13 > 15
... x > 2
If x is the longest side, ...
... 13 +15 > x
... x < 28
Then the allowed range for the third side is ...
... 2 < x < 28
To get roots of 13 and -3 the simplified equation will have to look like this.
(X-13)(X+3)=0
So if we multiply this out with foil method we get this:
X^2 -10X -39
So the answer is A

Answer:
Option c, 35
Step-by-step explanation:
<A and <B are supplementary,
so, <A+<B = 180
or, 3x-9+2x+14=180
or, 5x+5=180
or, 5x=175
or, x=35
