Answer:
c. 2a3+9a2+45a+6ab2+18b2
Step-by-step explanation:
(a+3) + (−2a2+15a+6b2)
Using distributed p. with and a and 3
a(−2a2) + a(15a) +a(6b2) and 3(−2a2) + 3(15a) + 3(6b2)
= -−2a3 + 15a2 + 6ab2 = -6a2 + 45a + 18b2
Now add like terms and put in standard form.
15a2+(-6a2) = 9a2
And equals
-2a3 + 9a2+45a+6ab2+18b2
Trust me I took the test and got 100%
Your welcome,
List this from least to greatest:.5, 3/16, .75, 5.48

<em>Greetings from Brasil...</em>
Here is the problem:
[(15X - 8)/3] + [(9X - 3)/2]
<em>Let's multiply everything by 6</em>
[6.(15X - 8)/3] + [6.(9X - 3)/2]
[2.(15X - 8)] + [3.(9X - 3)]
30X - 16 + 27X - 9
<h3>57X - 25</h3>
