The product of two negatives and one positive will give you a negative number. Take the three numbers; -1, -1, and 1. There are two negatives and one positive. 
-1 x -1 x 1 = 1 x 1 = 1 = positive number
So the possible answers are the positive numbers:

20 and 10

Hope this helps :)

The <em>correct answers</em> are:

20 and 10.

Explanation:

Multiplying two negatives results in a positive product. Multiplying this positive product by another positive number will result in a positive answer. This means the only possible answers from our choices are the two positive ones, 20 and 10.

Emily is thinking of a number, which she calls n. She finds 1/4 of the number and then subtracts 3.
Debora [2.8K]

Answer:

n/4 - 3 OR 1/4n - 3

Step-by-step explanation:

First, let's assign a variable to Emily's number.  Let is be <em>x</em>.

Now all we have to do is go through the problem step by step.

"She finds 1/4 of the number..."

There are two ways you can do this.  You can either multiply n by 1/4 (1/4n), or you can divide by 4 (dividing by four is the same as finding 1/4 of a number).  For this example let's divide by four

n/4

"...and then subtracts 3."

All we have to do is subtract 3 from n/4

n/4 - 3

REMEMBER: like I said, there are two possible options.  You can either have n/4 or 1/4n. They mean the same thing

Yvonne is solving the quadratic equation 6x2 + 24x + 7 = 0 by completing the square. Her first four steps are shown in the table
zaharov [31]
Step 1 should be
Bring the constant to the other side and divide the whole equation with 6 resulting to
x2 + 4x = -7/6

Step 3 should be
Complete the square by dividing the coefficient of x by 2, squaring it and adding the result to both sides of the equation.
x2 + 4x + 4 = -7/6 + 4

Step 4 should be
Factor the quadratic equation and simplify
(x+2)2 = -17/6

Step should be
Get the square root of booth sides and solve for the values of x
x+2 = +-√(102) / 6
So,
x = -2 + √(102) / 6 and x = -2 - <span>√(102) /3
