<span>Hello :)
6(x+3)=(x+3)+(x+3)+(x+3)+(x+3)+(x+3)+(x+3)
Six times some number plus 3 is 42.</span>
The degree of a polynomial is the highest power.
In the polynomial we are given, the only power is 2 which makes it greatest.
Therefore, the degree is 2.
Best of Luck!
Just work with it as seperate triangles and then add them up.
