I WILL GIVE BRAINLIEST AND THANKS SOLVE THE QUADRATIC EQUATION
laiz [17]

Answer:

x = -0.907, 2.57

Step-by-step explanation:

Quadratic Formula: x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}

Since we are given <em>a</em> = 3, <em>b</em> = -5, and <em>c</em> = -7 from our quadratic, we simply use the Quadratic Formula:

Step 1: Plug in variables

x=\frac{-(-5)+/-\sqrt{(-5)^2-4(3)(-7)} }{2(3)}

Step 2: Solve

x=\frac{5+/-\sqrt{25+ 84} }{6}

x=\frac{5+/-\sqrt{109} }{6}

Step 3: Evaluate for decimals

You should get x = -0.906718 and 2.57338 as your answers.

Find the number of unique permutations of the letters in the word: ONGOING
Kazeer [188]

Answer:

<h2>The Number of unique permutation is  6,615</h2>

Step-by-step explanation:

  This particular permutation  deals with words that have repeated letters.

Given word = "ONGOING"

the formula for the permutation is

= \frac{n!}{mA! mB!.....mZ!}

where   n   is the amount of letters in the word, and  m A , m B , ... , m Z  are the occurrences of repeated letters in the word. Each   m  equals the amount of times the letter appears in the word.

So in the word  "ONGOING"

n= 7

mO= 2

mN= 2

mG=2

permutations = \frac{7!}{2!2!2!} \\\\permutations= \frac{7*6*5*4*3*2*1}{(2*1)*(2*1)*(2*1)}

permutations=  \frac{52920}{8} \\permutation = 6,615

Can y'all answer this please n–2 1/2=7 1/2
Yuki888 [10]
Hi!
So this is an algebra question. We basically want to know what number minus 2 and 1/2 is going to equal 7 and 1/2. An easy way to check for that first number is adding those two numbers together

So we take 2 and 1/2 + 7 and 1/2 , and because they have the same denominator we can add the two numbers . 2 + 7 = 9 and then 1/2 + 1/2 = 1 so 9+ 1 = 10

10- 2 1/2 = 7 1/2
