That is all the problem states with no numbers

Can you please add more information please? I don't know what numbers to use, so please include more information?

Distributive 17 throughout the  y² + 8y - 2    

               --->  17(y²)  +  17(8y)  -  17(2)

               --->  17y²  +  136y  -  34

So you have:    12y  +  17y²  +  136y  -  34

Combine the  12y  with the  136y

to get     17y²  +  148y  -  34

2.5 cm ≈ 1 in

You can use a ruler too. But the exact measurement is:

2.4 cm = 1 in

1 in  =  2.54 cm

Start by writing  x^n as e^(n lnx ).

d( x^n )/dx  =  d( e^(n lnx ) )/dx

                   =  e^( n ln x ) · d( n ln x )/dx                        chain rule

                    = x^n · ( n/x )

                    = n · x^( n - 1 )

use powers of ten, like for 875 do 8 X 10 to the power of 2 plus 7 X 10 plus 5 X 1

So, you're on a PC? But thank you. I will do it later.

Use the "x to the y" key, found right below the "e" key.

yeah the pic is on a pc and its way better there

It still won't work. I will go on my PC and do it there.

But thanks.

To calculate invsin, hit the (2nd) button and then the (sin) button and then enter the number.

Similar for cos and tan.

There are two ways:

First way:  multiply the original number by  2  and then divide that answer by  3.

Second way:  divide the original number by  3  and then multiply that answer by  2.

-61  =  -7 ( 3b + 1 ) - 6b

Use the distribuitve property on -7 ( 3b + 1)   to get    -7(3b)  +  -7(1)    to get    -21b - 7

-61  =  -21b - 7 - 6b  

Combine the  -21b - 6 b  to get  -27b

-61  =  -27b - 7

Add 7 to both sides:

-61 + 7  =  -27b - 7 + 7

-54  =  -27b

Divide both sides by -27   -->  -54 / -27  =  2

2  =  b

In an equation such as  y  = 2x + 1,  

the x is the "independent" variable because you can enter any number for x,

while the y is the "dependent" variable because its value is dependent upon the number that you entered for x.

In an experiment, such as determining how many calories that you burn per hour of one particular type of exercise,

the numer of hours that you exercise is the independent variable,

while the number of calories burned is the dependent variable. 

If you work for a wage, the number of hours worked is the independent variable while the amount earned is the dependent wage.

On the calculator on this site, the negative button and the minus button is the same button.

If you give back $1 for every $2 that you make, you will have to give back half the money that you've made.

How much is one-half of $4000.00? That's the amount that you will have to give back.

To write  14 3/4   as a common fraction:

   --  to get the numerator, multiply 14 x 4 and add 3  -->  56 + 3 = 59

   --  the denominator is 4

Therefore,  14 3/4  =  59 / 4

Now:  to divide, multiply by the reciprocal  (the reciprocal of  3  is  1 / 3)

   59 / 4 ÷ 3     --->   59 / 4  x  1 / 3

To solve, multiply the numerators together ( 59 x 1 ) to get 59

and multiply the denominators together (4 x 3 ) to get 12

So, the answer is 59 / 12

To write this answer as a mixed number: Divide  59  by  12  to get a quotient of  4  and a remainder of  11:

4 + 11 / 12

Do you mean √1 x (10^19)   which is  1 x ( 10^19 )  which is just  10^19     (a 1 followed by 19 zeroes)

or  √( 1 x 10 ) ^ 19   =   √10 ^ 19        which is 3 162 277 660  (approx) 

Mixed number are like this:  5 1/4

You can change it into a decimal by dividing 4 into 1 to get .25 and then add that to 5 to get  5.25

You can change it into a common fraction by multiplying the 5 times 4 and then adding the one,

to get 21 / 5.

If you want more specific instructions as how to add or subtract or multiply or divide mixed number, please post again.

Use a calculator to evaluate   1.012 ^ 5

which beomes  1.061457384

when rounded becomes 1.061

"i"  usually represents  "√-1"

So a number written as 3 + 4i means 3 + 4√-1

This means that you have a "complex" answer; the 3 is the "real" part andthe "4i" is the imaginary part.

sin*csc(3) isn't an appropriate expression.
