The product of two numbers is 144, but their sum is -24. What are these two numbers?

The two numbers are - 12 and - 12 .

Step-by-step explanation:

Let the two numbers be x and y then

By the question

x * y = 144

or x = 144 / y I)

Again

x + y = - 24

Or 144/y + y = - 24

or, ( 144 + y²) / y = - 24

or, 144 + y² = - 24y

y² + 24y + 144 = 0

y² + ( 12 + 12 ) y + 144 =0

y² + 12y + 12y + 144 = 0

y(y + 12 ) + 12 ( y + 14) = 0

( y + 12 ) ( y + 12 ) = 0

Either

y + 12 =0

y = - 12

Now

x = 144 / - 12 = - 12

Therefore the two numbers are - 12 and - 12 .

Hope it will help :)❤

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
