Multiply (3a + 5)2
A9a2 + 30a + 25
B 25a2 + 15a + 9
C a2 + 3a + 25
D 5a2 + 15a + 9

9 a^2 + 30 a + 25 the anwser is A

Step-by-step explanation:

Expand the following:

(3 a + 5)^2

(3 a + 5) (3 a + 5) = (3 a) (3 a) + (3 a) (5) + (5) (3 a) + (5) (5) = 9 a^2 + 15 a + 15 a + 25 = 9 a^2 + 30 a + 25:

9 a^2 + 30 a + 25
