Simplify the expression.

12 x [(9 + 6) / 3}

a.
38

b.
54

c.
60

d.
110

answer: need a picture

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
