We want to select a committee of five members from a group of four women and six men. The order of selection is irrelevant. How many committees can we make with Jack as committee chair? (Assume that only one member has that namel)
committees

the solution is h=10 because you add 9 to each side of the equation.

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
