Answer:
-2a³+9a²+45a+6ab²+18b²
Step-by-step explanation:
(a+3)(-2a²+15a+6b²)
Distribute the a:
-2a³+15a²+6ab²
Then distribute the 3:
-6a²+45a+18b²
Now add both of the results together:
-2a³+15a²+6ab²-6a²+45a+18b²
Combine like terms:
-2a³+9a²+45a+6ab²+18b²

Answer:
19
Step-by-step explanation:
f(x)=2/3
2/3=-1/3x+7
Subtract 7 from both sides
2/3-7=-1/3x
-6 1/3 = -1/3x
Multiply both sides by -3
-3(-6 1/3)=-1/3x(-3)
19 = x
It would be the last one because 5 columns are shaded and there are 10 columns all together. 50/100= 0.5
