What two numbers multiply together and equal 16 and add together and equal -2?

Answers

Answer 1

Answer: There is a solution, but you might not have learned how to do it yet
in middle school.

If you've learned to use the quadratic formula to solve a quadratic equations,
then you can do this.

The first requirement says: ' x ' times ' y ' = 16
The second requirement says: (x + y) = -2

Take the second requirement, and subtract ' x ' from each side:

y = -x - 2

Substitute this into the first requirement:

' x ' times (-x - 2) = 16

Eliminate parentheses:

-x² - 2x = 16

Subtract 16 from each side:

-x² - 2x - 16 = 0

Multiply each side by -1:

x² + 2x + 16 = 0

Solve this with the quadratic formula, and you get two solutions,
which are the two numbers that satisfy both requirements.

The numbers are

-1 + √-15

-1 - √-15

Check:

-- Product: (-1 + √-15) times (-1 - √-15) = 1 + 15 = 16

-- Sum = -1 + √-15 -1 - √-15 = -2

They work.
yay

Answer 2

Answer: None, because both numbers must be negative in order to get a positive answer, or both positive. However, -2 means that there is at least one negative number, or two negative numbers. the only option : -1+(-1)= -2. So there is no real solution.

If the area is 30 inches. What is the perimeter

Answers

If the area is 30 inches, then the length must be 5 and the width must be 6, so 10+12=22 which is your perimeter. I got 10 with 5x2 and 12 with 6x2. Then you add it together because the formula for perimeter is (lengthx2) +(widthx2)! Just in case you need an explanation.

You would beed to say how long the width and kength is. There are a lot of different answers to that question without a specific width or length
