Add.

(9a+6)+(a+4)

10a + 10

(4c2+9c+9)–(4c2+5c+5)

Simplifying the expression by removing the brackets and combining like terms, we get:

(4c^2 + 9c + 9) - (4c^2 + 5c + 5)
= 4c^2 - 4c^2 + 9c - 5c + 9 - 5
= 4c

Therefore, the simplified expression is 4c.

(2r²+9r+9)–(r²+7r+5)

Simplifying the expression by removing the brackets and combining like terms, we get:

(2r² + 9r + 9) - (r² + 7r + 5)
= 2r² - r² + 9r - 7r + 9 - 5
= r² + 2r + 4

Therefore, the simplified expression is r² + 2r + 4.
