Daniel expanded the expression as shown.
-2(-8x-4y+3/4=-10x-8y-1 1/4
a. what errors did he make? check all that apply.
b. the first term should be positive.
c. the second term should be positive.
d. he did not distribute the -2 properly.
e. he added -8 and -2 instead of multiplying -8 by -2.
f. he did not simplify the expression completely.
g. the last term should be -1 1/2, not -1 1/4.

i dont know but hope u do

step-by-step explanation:

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

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

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
