I got a 1/2. Which one did I get wrong? Please help

Step-by-step explanation:

Right away, because the scale factor of the dilation is 1/2, which is less than 1, the new surface area should be less than the original.  Simply multiply each side length by 1/2, then recalculate for surface area to get 4*4*6, or 96.

Hope it helps :) and let me know if you want me to elaborate.

i will take them

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
