I think you teacher may be wrong again. 

I'm pretty confident it's 15 1/6

=^._.^=

Ok it was 14.95.

the question was a typo

well do you know how to get 14.95?

Area

length = 6 1/2 = 13/2

Height = 2 1/3 = 7/3

we need to find length * height = 13/2 * 7/3 = 91/6 = 15 1/6

Idk how you would have 10 1/2

I think the question may be worng.

Well I am going to email my teacher

Area

I'm sorry, I don't think I understand. :((

What are you looking for, like the area or perimeter?

=^._.^=

That is the question

what is the question?

=^._.^=

I mean like the answer is 10 1/2 but I don't know how do you get that answer 

I'm not quite sure what you mean by "how to get 10 1/2 in"

To find the area, you want to multiply  6 1/2 * 2 1/3 = 13/2 * 7/3 = 91/6

To find the perimenter, you want to add  6 1/2 + 2 1/3 + 6 1/2 + 2 1/3 = 39/6 + 14/6 + 39/6 + 14/6 = 106/6 = 53/3

I hope this helped. :))

1 - 1x + 2x^2  - 2 + 3x -  3x^2  +  4  - 4x   + 5x^2     collect like terms

5x^2  - 3x^2 + 2x^2   - 4x + 3x  - 1x   +  4  -  2  +  1

4x^2   - 2x  +   3

a  =  4

b  = -2

c = 3

a + b +  c  =   4  - 2  + 3    =     5

We need to combine like terms. 

(2x^2-3x^2+5x^2) + (-1x + 3x - 4x) + (1 - 2 + 4)

4x^2 - 2x + 3. 

4-2+3 = 5

I hope this helped. :))

There are a ton of people on here, so it just seems like people are on 24/7. 

As for doing daily stuff, I'm still a student so I don't have many things to do. 

Also, answering questions helps me practice my math.

I think of it as a win-win situation, I get to practice, and other people get help. :))

y = mx + 1

y = 2/3x + 1

That's our line equation. :))

n^2 = 2/3n + 1

3n^2 = 2n + 3

3n^2 - 2n - 3 = 0

Can you solve for the 2 values of n from here?

We  have  a circle  with a center  of  (-2, 7)   and a radius  of  13.......the  equation is

(x + 2)^2  + (y - 7)^2   =   13^2

Manipulating the equation of the line   we  have  that  x  = 2y + 10

Sub  this  into  the  circle equation 

(2y + 10 + 2)^2  +  ( y - 7)^2  =   13^2

(2y + 12)^2  +  ( y - 7)^2  =   169

4y^2  + 48y  + 144  + y^2  - 14y  +  49  = 169

5y^2 + 34y  + 24  =  0          factor

(5y  + 4) ( y + 6)   =  0

Set  each  factor  to  0  and  solve  for  y

5y + 4  =  0                                 y  +  6   =   0

5y  =  - 4                                    y  =  - 6

y  =  - 4/5

And

x = 2 (-4/5) + 10                             x  = 2(-6) + 10

x =  -8/5  + 50/5                              x  =   -2

x =  42/5

The  intersection points  are  (-2, - 6)   and  (42/5,  -4/5)

Book = x

CD = 6x

x + 6x = 56

7x = 56

x = 8

Difference = 5x. (6x-x)

5*8 = 40. 

I hope this helped. :))

Computer = 3/4x

Drama = x

Drama now = x/2

Computer now = 5/4x

5/4x = 27 + x/2

3/4x = 27

x = 36

I hope this helped. :))

YAYYYY!!!

The base of the triangle is 12, and the height is 10.5 :))

The area of a triangle is base * height / 2. 

Tell me what you get?

Please help me

thats wrong :(

x = total marbles

3/5 x  = 33

x = 33 * 5/3 = 55 marbles total

55 marbles
