Answer:
B
Step-by-step explanation:
48-19=29x2=58 so yeah thats how you do dat
7r³ - 3r² + 20r
(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)
You can get rid of the parentheses since there is nothing to distribute.
9r³ + 5r² + 11r - 2r³ + 9r - 8r²
Combine like factors.
(x + 3)(x + 4)
x^2 + 3x + 4x + 12
x^2 + 7x +12
