Question 7 of 10 Which of these groups of values plugged into the TVM Solver of a graphing
calculator will return the amount of a 25-year loan with an APR of 16.8%,
compounded monthly, that is paid off with monthly payments of $340?
A. N=300; 1%=1.4; PV = ; PMT=-340; FV=0; P/Y=12; C/Y=12;
PMT:END
B. N=25; 1%=1.4; PV = ; PMT=-340; FV=0; P/Y=12; C/Y=12; PMT:END
C. N=25; 1%=16.8; PV = ; PMT=-340; FV=0; P/Y=12; C/Y=12;
PMT:END
D. N=300; 1%=16.8; PV = : PMT=-340; FV=0; P/Y=12; C/Y=12;
PMT:END

step-by-step explanation:

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)

you,

mrb

(a + b) (a^2 - a b + b^2)

good luck on ur quiz test or homework. have a good day : )
