Hope this made it simpler for you

A variable is a letter that takes in place of a number. For example 2m+1= 5

The variable is "m"

Lets see this equation if we replace the letter with a number-

2 x 2 + 1= 5

"M" wouldve been the "2" in the equation.

Hoped this helped

All you have to do is distribute the number into the parenthesis. 

Whats 2m²? = 4m

Then, whats 1²? = 1

(2m+1)² = 4m+1

Hoped that simplified things out

3/(3 b+7) = 2/(b-7) cross multiply

3b - 21 = 6b + 14

3b = -21 -14

3b = - 35

b = -35/3 =-11 2/3

When the football hits the ground, the value of h will be 0.

Solving:  -16t² + 36t + 4  =  0

Using the quadratic formula with  a = -16   b = 36   c = 4:

t  =  [ -36 +/- sqrt( 36² - 4(-16)(4) ) ] / [ 2(-16) ]

t  =  [ -36 +/- sqrt( 1296 + 256 ) ] / [ -32 ]

t  =  [ -36 +/- sqrt( 1552 ) ] / [ -32 ]

t  =  [ -36 +/- sqrt(16)·sqrt(97) ] / [ -32 ]

t  =  [ -36 +/- 4·sqrt(97) ] / [ -32 ]

Dividing numerator and denominator by -4:

t  =  [ 9 +/- sqrt(97) ] / 8

Answer C.

25/20 =1.25 -1 =.25 x 100 =25% more time spent on his HW.

By saying "125% more time", he is saying that the extra time he spent was 125% of the orginal amount.

Last week he spent 20 hours. This week, he spent 25 hours, 5 more hours.

Comparing the extra hours (5) to the hours that he spent last week (20):  5/20  =  25% extra time.

The hours that he spent this week, when compared to the hours last week, is 125%; but this isn't 125% more time.  

Solve for b:
3/(3 b+7) = 2/(b-7)

Take the reciprocal of both sides:
1/3 (3 b+7) = (b-7)/2

Expand out terms of the left hand side:
b+7/3 = (b-7)/2

Expand out terms of the right hand side:
b+7/3 = b/2-7/2

Subtract b/2+7/3 from both sides:
b/2 = -35/6

Multiply both sides by 2:
Answer: |b = -35/3 =-11 2/3

25/20 =1.25 x 100 =125% He is right.

There The ratio of boys to girls is 4:5 there are 572 boys at the school how many children are there at the school

5/4 x 572 =715 are girls

572 + 715 =1,287 Number of children in the school.

How can the LHS = RHS when you have e^200 on the LHS compared to what you have on the RHS??.

6937920mins to days months year?

6,937,920mins / 60 minutes =115,632 hours

115,632 hours / 24 hours =4,818 days

4,818 days / 30.417 days =158.4 months

158.4 / 12 months =13.2 years.

wouldnt your f(x) be? \( f (x) = x^\frac{1}{3} + 2x^{-2016} + x^{-3/2}\)

Using polynomial division, we have

               2x +19

x - 12    [ 2x^2 -5x + 2 ]

               2x^2 -24x

              -------------------

                        19x + 2

                        19x - 228

                        ________

                                230

So the result is   2x + 19   +  [ 230] / [ x - 12]

Very nice explanation, Joshie.......!!!!

in order to do this question you need to know how many minutes there are in an hour, how many hours in a day how many days in a month and how many months in a year. I would first start out by converting the minutes into hours by the conversion.

there is 60 minutes in every hour so 

6937920/60=115632 This means you have 115,632 hours 

 Now lets convert this into days.

There is 24 hours in every day.

115,632/24=4,818 this means that 6937920 minutes is equivalent to 4818 days.

Now lets convert it into months. we know there is 365 days in a year and 12 months in this said year. We can take the 365/12 giving us an answer of 30.42 with rounding. This number tells us how many days are in an average month.

Now the conversion 4818 days divided by 30.42 days in every month is equal to 158.3826. This means 6937920 minutes is equivalent to 158.38 months.

Convert that into years by dividing 158.38 by 12 considering there is 12 months in every year. This is equal to 13.19855358 which if rounded is roughly 13.2 years.

Overall:

6937920 minutes

115,632 hours

4818 days

158.38 months

13.2 years

Find the derivative of the following via implicit differentiation:
d/dx(f(x)) = d/dx(2/x^2016+1/x^(1/3)+x^(1/3))
The derivative of f(x) is f'(x):
f'(x) = d/dx(2/x^2016+1/x^(1/3)+x^(1/3))
Differentiate the sum term by term and factor out constants:
f'(x) = 2 d/dx(1/x^2016)+d/dx(1/x^(1/3))+d/dx(x^(1/3))
Use the power rule, d/dx(x^n) = n x^(n-1), where n = -2016: d/dx(1/x^2016) = d/dx(x^(-2016)) = -2016 x^(-2017):
f'(x) = d/dx(1/x^(1/3))+d/dx(x^(1/3))+2 (-2016)/(x^2017)
Simplify the expression:
f'(x) = -4032/x^2017+d/dx(1/x^(1/3))+d/dx(x^(1/3))
Use the power rule, d/dx(x^n) = n x^(n-1), where n = -1/3: d/dx(1/x^(1/3)) = d/dx(x^(-1/3)) = -1/3 x^(-4/3):
f'(x) = -4032/x^2017+d/dx(x^(1/3))+(-1)/(3 x^(4/3))
Use the power rule, d/dx(x^n) = n x^(n-1), where n = 1/3: d/dx(x^(1/3)) = d/dx(x^(1/3)) = x^(-2/3)/3:
f'(x) = -4032/x^2017-1/(3 x^(4/3))+(1)/(3 x^(2/3))
Expand the left hand side:
Answer: |f'(x) = -4032 / x^2017-1 / (3 x^(4/3)) + 1/(3 x^(2/3))

Expressing this in exponential form, we have :

f (x) = x^1/3 + 2x^-2016 + x^-1/3        use the power rule here

f ' (x)   = (1/3)x^-2/3 - 4032x^-2017 - (1/3)x^-4/3

you mean solve?? and its (2x² -5x +2) / (x-12) 

So 2 - 12 = (-10) you cannot add or subtract unlike terms. so far you have 2x² -5x / x-10 so (-5x) / x = -5x so you have 2x² -5x -10 as your simplified expression, add a final answer to simplify it further and get the value of x. 

LOL!! I was thinking the same but i was like "bro this is math not science.." For an original FRACTION lol idk..... what you mean by that??

3.14*32

you could mean 2 things here. are you trying to convert this into a percent or are you multiplying this by a percent. They are different answers.

(50/300)x100%=1/6

or

(50/300)x100=16.66666666667% or 16.7%

"What is the slope of line m??"

x + 3y = 6   rearrange as

3y = - x + 6           divide both sides by 3

y  = -x/3 + 2

y = (-1/3)x +  2      so.....the slope is -1/3
