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

Answer:
-4<-1 and -1<4
Step-by-step explanation:
1. Divide cost by the pounds so you get the cost of one pound:
1.25 / 2.5= .5
1 pounds of bell peppers costs .50$
2. The beef cost most per pound: 9.56 / 4=2.39
3. He would have paid 11.05 for 8.5 pounds because when you divide 15.30 by 8.5 to get cost per pound and subtract .5 to get .50$ less per pound, then multiply by 8.5 to get the cost for 8.5 pounds, you get 11.05$
