8m - 5.5 =10.1

Help Please

= 1.95

Step-by-step explanation:

8 − 5.5 + 5.5  = 10.1 + 5.5

8 = 15.6

8 = 15.6

8         8

first 5.5 means 55/10 and 10.1 means101/10 when we change them to fraction.

8m=101/10+55/10=156/10

divide 8 by 8 and we get m

and again divide 156/10 for 8

m=1.95

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)

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

is there more to this question?
