Aplumber had a pipe that was 2 \text { yards}2 yards long. he cut 18 \text{ inches}18 inches off the end of the pipe. how many feet long was the pipe after the plumber cut it?

4.5 feet of pipe after he cuts it

Step-by-step explanation:

You multiply 2 by 36 to get inches then subtract 18 which is 54 inches and then you divide by 12 to turn it into feet and you get 4.5

it’s supposed to be -4+45=41

step-by-step explanation:

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.

you,
