What number multiplies to -5 and adds up to 6

The two numbers are and .

Step-by-step explanation:

I am assuming you meant "numbers", otherwise you question has no answer.

Let us call the two numbers and , then we have

(1).  (they multiply to -5)

(2). (they add to 6}

We solve for   and , by first solving for in equation (1):

and substituting this value into equation (2):

multiply both sides by and rearrange to get:

Using the quadratic formula we solve for to get:

which when put into equation (1) give

.

Thus, the two numbers are and .

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

16 is the absolute value
