Simplify the following expression.

7(2y + 5z) - 35z
A.
9y
B.
14y - 40z
C.
9y - 70z
D.
14y

14y

Step-by-step explanation:

7 times 2 = 14

7 times 5 = 35

14y + 35z - 35z

35 - 35 = 0

You are left with 14y

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

da freeck kinda math is this just drop out
