All of my points to anyone who can me with marking brainliest as well

Question one 186

Question two 240

Step-by-step explanation: You multiply the variable (the letter) by the number that the person is using

1. 186

2. 240

Step-by-step explanation:

1. D =3w+60

D =3(42)+60

D =186

2. I =48t

I =48(5)

I =240

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
