Kara is sorting buttons by length for a craft project. The line plot shows the length of each button. If Kara lines up all the 3/4 inch buttons, what would be the total length?

The total length would be  

Step-by-step explanation:

The line plot figure is missing in the question, so below is the figure attached.

Now, to find the total length, if Kara lines up all the inch buttons.

So, from below figure we see that in the line plot inch buttons represents 3 buttons.

Length of buttons = inch.

Number of buttons = 3.

Now, to get the total length of inch buttons we multiply length of buttons by number of buttons:

Therefore, the total length would be

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
