An expression is shown
3a(a + b  5) + 4(2a + 2b) + b(a + 3b  7) Which expression is equivalent to the expression shown? A.) 11a² + 3b²  2ab + 7a + b B.) 11a² + 3b²  4ab + 7a = b C.) 3a² + 3b²  2ab + 7a + b D.) 3a² + 3b²  4ab + 7a + b
3a(a + b  5) + 4(2a + 2b) + b(a + 3b  7)
= 3a²  3ab + 15a  8a + 8b + ab + 3b²  7b {used distributive property} = 3a² + 3b²  2ab + 7a + b {combined like terms} Ask Algebra House Comments are closed.
