maybe 3x
Step-by-step explanation:
D=20/3 or in decimal form d=6.666, it keeps going
Answer:
Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.
<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>


<em>Now solve what remains in the parentheses.</em>


<em>Finally, subtract 4 from 10 and get your answer:</em>
6
Answer:2.75
Step-by-step explanation:
Answer:
x=√139-3, x=-√139-3
Step-by-step explanation:
to complete the square, you first move the constant to the other side of the equation-its already done for you!
now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.
What you do to one side has to be done with the other.
x^2+6x+9=130+9
now you can factor the square:
(x+3)^2=139
squareroot both sides:
x+3=√139
x+3=-√139
now subtract both sides by 3
x=√139-3
x=-√139-3
