Answer 7

Answer 8

Thks :D

Answer 9

\[(5a+3b+9c)^2\]
\[(5a+3b+9c)(5a+3b+9c)\] Go one by one, take the first term in the first bracket and the multiply by each term in second bracket, then take the second term in the first bracket and multiply it by each term in the second bracket, then take the third term in the first bracket and multiply it by each term in the second bracket.
\[25a^2+15ab+45ac+15ab+9b^2+27bc+45ac+27bc+81c^2\]
Now combine like terms:
\[25a^2+30ab+90ac+9b^2+54bc+81c^2\]
This is the final anser
