Match each piece of text from a personal narrative essay to the section of the essay where it belongs. back on that day, I’m glad Grandma made me do it. Entering that spelling bee changed my life. Standing in front of hundreds of people wasn’t easy. But thanks to Grandma, I no longer have stage fright. arrowRightHave you ever done something that scared you? Have you ever done something that you can’t believe you did after it was over? I have. When I was in 5th grade, I participated in the school spelling bee. arrowRightGrandma and I quizzed each other on difficult spelling words every night. We even made a list of favorite words that we had never heard before. arrowRightAnswer

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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