v On a coordinate plane, triangle A has points (negative 2, 0), (negative 6, 0), (negative 4, 4). Triangle A prime has points (1, 0), (3, 0), (2, negative 2). Which describes the sequence of transformations used to obtain the image (triangle A’) from the pre-image (triangle A)? dilation by a scale factor of 2, then rotation of 180° about the origin dilation by a scale factor of 2, then a reflection over the x-axis dilation by a scale factor of 1/2, then a rotation of 180° about the origin dilation by a scale factor of 1/2. then a reflection over the x-axis

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

hello from mrbilldoesmath!

answer:

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

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

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

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

he answer is x=1x3 because x=1 to x=3
