15 - 4x = 6 - 3x<br><br>whats the answer.

Makovka662 [10]

Answer:9

Step-by-step explanation: First you add the 3x to both sides(the -4x and the -3x) and then you get 15-1x=6. Next you subtract 15 from 15 and 6, so you get -1x=-9. So then you divide both sides by -1 (do -1x over -1 equals -9 over -1). Last you do the dividing and you get x=9.

What two numbers add to 13 but multiply to negative 12?

Phoenix [80]

9514 1404 393

Answer:

13.8654599313 and -0.8654599313

Step-by-step explanation:

If one of the numbers is x, then the other is 13-x, and their product is ...

x(13 -x) = -12

x^2 -13x = 12 . . . . multiply by -1 and simplify

x^2 -13x +6.5^2 = 12 +6.5^2 . . . . complete the square

(x -6.5)^2 = 54.25

x -6.5 = √54.25

x = 6.5 +√54.25 ≈ 13.8654599313

and the other number is ...

13 -x = 13 -13.8654599313 = -0.8654599313

The two numbers are 13.8654599313 and -0.8654599313.

Row four: 1, 4, 6, 4, and 1

=========================================

Explanation:

Each value can be found in Pascal's triangle. You can also use the nCr combination formula to get each value. The nCr formula is

$_n C _r = \frac{n!}{r!(n-r)!}$

The value of n represents the row number. The r value is the column number, so to speak, for each row.
