Which ordered pairs are in a proportional relationship with (0.2, 0.3)?

A

(1.2, 2.3)

B

(2.7. 4.3)

C

(3.2, 4.8)

D

(3.5, 5.3)

E

(5.2, 7.8)

C and E

Step-by-step explanation:

We are given that

A.

Hence, it is not in proportional relationship with (0.2,0.3)

B.(2.7,4.3)

Hence, it is not in proportional relationship with (0.2,0.3).

C.(3.2,4.8)

Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).

D.(3.5,5.3)

Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).

E.(5.2,7.8)

Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).

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)
