What is the product?
(7x) (2x + 5)(x² - 4x-9)
14x5 – x4 - 46x® - 58x2 - 20%-45
14x6 – 56x5-91x4 - 140x2 – 315x2
14x7 - 56x6 – 126x + 35x4 – 140x® - 315x2
14x12 - 182x® + 35x4 - 455x2

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

maybe i can

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
