mash [69]
There is a 68.75% increase in the amount of water Nathan drinks from his usual 32 ounces. If he started drinking 54 ounces of water per day, then there is a 22 ounce increase in intake. And 22 ounces is 68.75% of 54 ounces. This percentage would be derived by using the formula (54-32)/32.

What is the discriminant in the quadratic equation x2 + 11x + 121 = x + 96? <br>      A. 0 B. 100 C. 20 D. 200
Maurinko [17]
Given:
x² + 11x + 121 = x + 96

First, we need to convert it into a quadratic equation.

x² + 11x - x + 121 - 96 = 0
x² + 10x + 25 = 0

a = 1 ; b = 10 ; c = 25

Quadratic formula:

x = (-b <u>+</u> (√b² - 4ac)) ÷ 2a

The discriminant is under the radical sign

discriminant ⇒ b² - 4ac ⇒ 10² - 4(1)(25) ⇒ 100 - 100 = 0

Correct answer is A. 0

7n-(4n-3) combining like terms with negative coefficient and distribution
sladkih [1.3K]

\huge\text{Hey there!}

\huge\textbf{Equation/Question:}

\mathbf{7n - (4n - 3)}

\huge\textbf{Convert equation/question to:}

\mathbf{= 7n - 1(4n - 3)}

\huge\textbf{Solving the equation/question:}

\mathbf{= 7n - 1(4n) - 1(-3)}

\mathbf{= 7n - 4n + 3}

\huge\textbf{Combine the like terms:}

\mathbf{= (7n - 4n) + 3}

\mathbf{= 7n - 4n + 3}

\mathbf{= 3n + 3}

\huge\textbf{Therefore, your answer should be:}

\huge\boxed{\frak{3n + 3}}\huge\checkmark

\huge\text{Good luck on your assignment \& enjoy your day!}
