9less than the square root of a number

Step-by-step explanation:

Let's break it down. There is..

-----------------------------------------------------

A square root of a number: (assuming "the number" is ).

And they say that 9 is less than that, so we subtract 9 from , which gives us .

I hope that helps! :)

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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
