Answer:

a - 2

Step-by-step explanation:

Perimeter = side 1 + side 2 + side 3

6a + 3 = 2(a + 3) + (3a - 1) + side 3

side 3 = (6a + 3) - (2a + 6) - (3a - 1)

side 3 = 6a - 2a - 3a + 3 - 6 + 1 = a - 2

6d^2+33d+27, what is the answer?

m_a_m_a [10]

$6d^2+33d+27 \\ \\ GCF = 3 \\ \\ 3( \frac{6d^2}{3} + \frac{33d}{3} + \frac{27}{3} ) \\ \\ 3(2d^2 + 11d + 9) \\ \\ 3(2d^2 + 9d + 2d + 9) \\ \\ 3(d(2d + 9) + (2d + 9)) \\ \\ 3(2d + 9)(d + 1) \\ \\$

The final result is: 3(2d + 9)(d + 1)
