Asteel company is making flat rectangular frames as a part of a new product they are launching. each frame will be cut out of a piece of steel and will have a final area as close to 28 cm2 as possible. the width of the frame needs to be uniform throughout. the inside dimensions of the frame must be 11 cm by 6 cm. complete the equation that models the above situation, and find the width of the frame, x

x = 0.76

Step-by-step explanation:

We can write the area of steel before it is cut as:

Area =

Expanding it by multiplying the brackets to get:

Area =

Area  area of steel before cutting =

Then we need the area of steel after 11*6 inside dimensions are cut out:

This area should be close to 28 cm, hence the equation becomes:

Moreover, plotting the graph gives us a value of x = 0.76.

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
