Answer:

C. (x-2)^2=7

Step-by-step explanation:

What you have to do first is to get rid of the 3 in the x^2 so you will divide 3 by the whole thing to get x^2-4x=3.

You will then divide -4 by 2 and then square the answer to get 4.

You will then add the 4 into the end of the equation and to the 3 to get x^2-4x+4=7.

You will then make into a perfect square (x-2)^2=7 and that is your answer.

Find the surface area of the tin game case
butalik [34]
To find the surface area you will need to find the area of all 5 surfaces (faces) on the prism.  On a triangular prism there are 2 triangular faces and 3 rectangular faces.  All 3 rectangular faces are the same and the 2 triangular faces are also the same.

To find the area of the triangular faces, you will use the formula for finding the area of a triangle:

A = 1/2bh
     1/2 x 10 x 8.7
A = 43.5 in^2 

To find the area of the rectangular faces, you will use the formula for finding the area of a rectangle:

A = bh
    10 x 3
A = 30 in ^2

30 + 30 + 30 + 43.5 + 43.5 = 177

The minimum amount of wrapping paper needed for the gift is 177 square inches.

A bulletin board has a perimeter of 200 inches. Which expression expresses the area A(w) of the bulletin board as a function of
mr Goodwill [35]

Answer:

area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

Step-by-step explanation:

  • let, the shape of the bulletin board is a rectangle,
  • then the perimeter of it = sum of all sides

= 2[length+width] = 2[l+w]

(let l: length, w : width )

  • so, 200 = 2[l+w]

100= l+w ( dividing both the sides by 2)

so, l= 100-w

  • area = length*width=l*w=[100-w]*w
  • therefore,area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

How do you simplify 2 15/10?
sdas [7]
First you take 15/10 and see that you can take 5 out of the top and bottom, so it would become 3/2. Now you have 2 3/2.   2 goes into 3 once with 1 remainder so 3/2= 1 1/2
So then you take the original 2 and add it to 1 1/2. The answer is now 3 1/2
