√5m / √5n =

(√5m * √5n ) / (√5n * √5n)

= (√(5m * 5n) ) / (5n)

= (√(25m * n) / (5n)

= √25 * √(m * n) / (5n)

= 5 * √(m * n) / (5n)

= √(m * n) / n

Given 5n² + 6n + 7 = n² - 4n : a. Find the value of the discriminant. b. State the number and type of roots/solutions/zeros.[2 r
Vika [28.1K]
\bf 5n^2+6n+7=n^2-4n\implies 5n^2+6n+7-n^2+4n=0
\\\\\\
4n^2+10n+7=0\\\\
-------------------------------\\\\
\begin{array}{llccll}
&{{ 4}}x^2&{{ +10}}x&{{ +7}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}

if you get a positive value, that means 2 real solutions
if you get 0, means 1 real solution only
if you get a negative value, is an imaginary root solution, same as saying no solution.

Answer:

p  ≥ -10

Step-by-step explanation:

Divide both sides by-9:

When dividing or multiplying by a negative number, always flip the inequality sign:

-9p/-9 > = 90/-9

Cancel out the negatives:

9p/9 > = 90/-9

Simplify the fraction:

p > = 90/-9

Simplify the signs:

p > = -90/9

Find the greatest common factor of the numerator and denominator:

p >= -10 · 9/ 1 · 9

Factor out and cancel the greatest common factor:

p > = -10
