Answer:
The three numbers are -1 6/7, -5 4/7, and 5 3/7
Step-by-step explanation:
The three numbers can be represented as...
x, 3x+11, and 3x
x+3x+3x+11=-2
7x+11=-2
7x=-13
x= - 1 6/7
3x= -5 4/7
3x+11= 5 3/7
first number = -2
second number = 5
third number = -6
Lets think first number is x , second number is y and third number is z.
B
10s^2-15s+20
<em> because 5(2s^2)=10s^2, 5(-3s)=-15s, and 5(4)=20</em>
