Question

1) p + 9; 4) x² - 3 x(x + 2) 2) 5) a-7 a +4 2y y-1 + 3 y + 6 3) 6) b-9 4 4 m² + 2​

Answer 1

1) p + 9 2) x² - 3 + x(x + 2) + 2 3) a - 7 + a + 4 + 2y + y - 1 + 3 + y + 6 4) b - 9 + 4 + 4 + m² + 2

These are all algebraic expressions that can be simplified further by combining like terms and performing any necessary operations. Without specific values for the variables, it is not possible to provide a single solution for each expression. However, the expressions can be simplified by combining like terms and performing any necessary operations.
