If c(x) = 4x - 2 and d(x)= x2 + 5x, what is (c. d)(x)?

4x^3 + 18x^2 - 10x.

Step-by-step explanation:

(c.d)(x) = (4x - 2)(x^2 + 5x)

= 4x^3 + 20x^2 - 2x^2 - 10x

= 4x^3 + 18x^2 - 10x.

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

8/k
