Which expression is equivalent to the expression below?(6c^2+3c/-4c+2)/(2c+1/4c-2)

Answers

Answer 1
Answer:

Answer:

-3c

Step-by-step explanation:

The given expression is:

((6c^(2)+3c)/(-4c+2))/((2c+1)/(4c-2))

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

((6c^(2)+3c)/(-4c+2))/((2c+1)/(4c-2)) \n\n =(6c^(2)+3c)/(-4c+2) * (4c-2)/(2c+1)\n\n=(3c(2c+1))/(-(4c-2)) * (4c-2)/(2c+1)\n\n =-3c

Thus, the given expression in simplified form is equal to -3c
Answer 2
Answer:

Answer:

-3c

Step-by-step explanation:

We are given that an expression

((6c^2+3c)/(-4c+2))/((2c+1)/(4c-2))

We have to find an expression which is equal to given  expression

Taking common 3c from nominator and -2 from denominator in dividened  and 2 common in divisor then we get

((3c(2c+1))/(-2(c-2)))/((2c+1)/(2(2c-1)))

(3c(2c+1))/(-2(2c-1))* (2(2c-1))/((2c+1))

By reciprocal divisor

By canceling same factor

Then ,we get

((6c^2+3c)/(-4c+2))/((2c+1)/(4c-2))

=-3c

A chef has some broccoli, cauliflower, carrots, and squash to make a vegetarian dish. List the possible combinations if he uses only 3 vegetables in the dish.

Answers

1. broccoli, cauliflower and carrots
2. squash, carrots and cauliflower
3. cauliflower, carrots and squash
I'm not going to type all the combination. So basically you have to multiply the vegetables by the number 3. So 3 x 4 is 12. Therefore he could do it in 12 different ways. Hope this helped. 

If original price is $0.75 and sale price is $0.15 what is the discount ?

Answers

Hi

0.75 ⇒ 100%
0.15 ⇒ x%

0.75x = 100·(0.15)
0.75x = 15
x = 15/(0.75)
x = 1500/75
x = 20%

100% - (discount) = x%
100% - (discount) = 20%
discount = 100%-20%
discount = 80%

Answer: 80%

Answer:

80%

What is the value of x in x/7 = 35

Answers


Try multiplying each side of the equation by  7 .
Then you must quickly step to one side, as the
answer jumps off the page at you.
x / 7 = 35

Multiply both sides  by 7 :

7*( x / 7 ) = 7 *35

Refine:

x = 245

How many times does the minute hand move around the clock face in one day?

Answers

The hour hand will go around the clock twice during a day, every 12 hours. During a single rotation, the minute hand will go around 12 times. The minute hand will pass the hour hand 11 times in the first 12 hours, and 11 times in the second 12 hours. This means that they will meet 22 times.
To find that, we will start from one minute. How many seconds are there in one minute? There are 60 seconds in one minute.
Now, how many minutes are there in an hour? 60 minutes. So we have to do 
60 × 60 = seconds in an hour = 3600 seconds
How many hours are in a day? Well, there are 24 hours in a day.
So 3600 × 24 = seconds in a day = 86400 seconds in a day

There are 86400 seconds in a day.

What is 350/100 as a decimal and percent?

Answers

350/100 would convert to 3.5 as a decimal and it would be 350%. Tip: An easy way to turn a decimal to a percentage is to just move the decimal point two place holders to the right, and if there is no number in the placeholder just make it a 0.
350/100 as a decimal is 3.5 but I'm not sure about the percentage.  Srry:(
