The required polynomial is:-4x^2-2x+15

Step-by-step explanation:

Let P be the polynomial that has to be found

Given

One polynomial = 5x^2-3x-9

Sum of both polynomials = x^2-5x+6

So,

(5x^2-3x-9) + P = x^2-5x+6\\P = x^2-5x+6 - (5x^2-3x-9)\\P = x^2-5x+6-5x^2+3x+9\\P = x^2-5x^2-5x+3x+6+9\\P = -4x^2-2x+15

Hence,

The required polynomial is:-4x^2-2x+15

A high speed pump can empty 4/7 of a tank in 20 minutes. How many minutes would it take to pump empty an entire tank?
Sphinxa [80]
Now, a whole in sevenths, will just be 7/7.

now, we know the pump can do 4/7 of the tank in 20 minutes, how many minutes will it take to do 7/7, or the whole tank?

\bf \begin{array}{ccll}&#10;\stackrel{part}{tank}&minutes\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;\frac{4}{7}&20\\\\&#10;\frac{7}{7}&m&#10;\end{array}\implies \cfrac{\quad \frac{4}{7}\quad }{\frac{7}{7}}=\cfrac{20}{m}\implies \cfrac{4}{7}\cdot \cfrac{7}{7}=\cfrac{20}{m}\implies \cfrac{4}{7}=\cfrac{20}{m}&#10;\\\\\\&#10;4m=140\implies m=\cfrac{140}{4}\implies m=35
