First, let's use the distributive property on 3(a+5)
3(a + 5) = 3a + 3(5) = 3a + 15
Now, let's go back to the inequality
3(a+5) < 9
Use the distributive property
3a + 15 < 9
Subtract both sides by 15
3a < -6
Divide both sides by 3
a < -2
That's your answer.
Have an awesome day! :)

Step-by-step explanation:
Hope this helps if does not im really sorry.
2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
