Dominic is cutting a rectangular hole in his paper, from top left corner to the bottom right corner. The rectangle will be 4.5 cm long and 3.5 cm wide. which of the following is closest to the distance between the corners of the rectangle?

Step-by-step explanation:

So initially you have a square piece of metal, 15" x 15". You cut out squares from the corners of each side with side length x.

So you'll have a sheet that looks something like this now (assuming the formatting works):

__|       |__

|               |

|__        __|

   ||

Your original side length was 15, but it has now been reduced by x on each side, so you're now going to have a new side length of 15 - 2x

When you fold the box up, the box will have a height of just x.

So you have a base with lengths (15 - 2x) and (15 - 2x), and a height which is just x.

V = l*w*h

So

V = (15 - 2x)(15 - 2x)(x)

= 225x - 60x^2 + 4x^3

Hope this helps

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
