Riddle 1 is 436.
Riddle 2 is 79
Step-by-step explanation:
in isoscles triangles two angles and lengths are equal .
two sides equal 3.5
so both of the angles are 55°
the sum of the angles in a triangle is 180°, so
x = 180° - 55° - 55°
x = 70° (Ans)
The product of 15 and
![x+4](https://tex.z-dn.net/?f=x%2B4)
is
![15(x+4) = 15x+60](https://tex.z-dn.net/?f=15%28x%2B4%29%20%3D%2015x%2B60)
. This is a linear binomial.
![4x^3-2x-9-(2x^3)](https://tex.z-dn.net/?f=4x%5E3-2x-9-%282x%5E3%29)
is a cubic trinomial. In your original question, I'm not sure what the
![5x+3](https://tex.z-dn.net/?f=5x%2B3)
means.
