What are the vertex, axis of symmetry, maximum or minimum value, and range of y = 3x2 + 6x - 1? O A. (1.4); x = 1; max: 8; range: ys 8
O B. (-1,-4); x = -1; min: -4; range: y 2 -4
O C. (-1,4); x = -1; min: 4; range: y24
O D. (1.-4): x = 1; min: 1; range: y = 1

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

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)
