Answer:
2(x^2+9)
Step-by-step explanation:
2x^2 +18
Factor out a 2
2(x^2+9)
For any triangle, the 2 shortest sides added together have to be longer than the longest sides.
short side (10) + short side (5) needs to be greater than (>) longest side (20)
10 + 5 > 20
15 > 20
This inequality is incorrect, so the lengths cannot make a triangle.
Hope this helps :)
