Answer 1

Answer #1- Add the expressions. 3x^2+2x−5+(−4+7x^2), Remove unnecessary parentheses. 3x^2+2x−5−4+7x^2, Add 3x^2 and 7x^2. 10x^2+2x−5−4, Subtract 4 from −5. 10x^2+2x−9.

Final Answer: 10x^2 +2x−9 hopefully you now get an understanding of how to do it.

Answer #2: 7x−9

Answer #3: 4(11x+5)

Answer #4: 15x-1

Answer #5: 22x-9
