pishuonlain [190]

Answer:

84\text{ in}^2.

Step-by-step explanation:

We have been given that  Mrs. Chen's students are making and decorating gift boxes for a nursing home. The boxes are 7 inches wide, 7 inches long, and 7 inches high. We are asked to find the amount of cardboard that is needed for each box.

We will use surface area of cuboid formula to solve our given problem.

SA=2(lw+lh+hw), where,

l = Length,

w = Width,

h = Height

SA=2(7\text{ in}\cdot7\text{ in} +7\text{ in}\cdot7\text{ in}+7\text{ in}\cdot7\text{ in})

SA=2(14\text{ in}^2+14\text{ in}^2+14\text{ in}^2)

SA=2(42\text{ in}^2)

SA=84\text{ in}^2

Therefore, Mrs Chen needs 84 square inches of cardboard.

the model represents a polynomial of the form ax2 bx c. an algebra tile configuration. 4 tiles are in the factor 1 spot: 3 x , 1
boyakko [2]

The equation modeled is  3x^{2} -4x+1=(3x-1) (3x-1)

The given equation Much easier to understand with the symbol                   3x^{2} -4x+1=(3x-1) (3x-1)

x   x  .x  -1  

x   x² x² x² -x

-1  -x -x- x  +1

That is how I interpreted the "tile" set up.

Now count up the factors:  

There are 3 x² . There are 4 -x and  a  +1

That's the third answer choice.
