2x2 + 6y – 2x – 6 + 3y + 10
the degree of the simplified polynomial is

8+9y-2x

Step-by-step explanation:

2×2+6y-2x-6+3y+10

Multiply

4+6y-2x-6+3y+10

calculate collect like terms

Solution:8+9y-2x

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
