you can calculate the sum of the area of the faces. start with the bottom which is a square with a length of 6. what would be the area?
ayyookyndall
  • ayyookyndall
36?

yes. and then you have 4 identical triangles. can you calculate the area of one of the triangle if the height is 9 and the base is 6? then multiply it by 4
ayyookyndall
  • ayyookyndall
Wait, 54 x 4 = 216

Is that it? Thats the answer?
nikato
  • nikato
no. 27 is just the area of one of the triangels but since you have 4, you muliply 27x4 then you add 36 because you still have that square base
ayyookyndall
  • ayyookyndall
So 27 x 4 = 108 108 + 36 = 144
ayyookyndall
  • ayyookyndall
144 is the answer
nikato
  • nikato
correct

You simply apply the given rule for each point of the triangle ABC Let me know wat you get ? :)
ayyookyndall
  • ayyookyndall
Whats the rule? Im confused.
nikato
  • nikato
(x+2) means that the triangle moves right. (y-2) measns that the triangle moves down. so look at all your graph. in which one is the graph moved right and down
anonymous
  • anonymous
The rule is : replace each x with x+2 and each y with y-2, ie: if you have a point like this: (7 , 4) then after applying rule you get : (9,2) :)
ayyookyndall
  • ayyookyndall
C moved right and down
nikato
  • nikato
are you sure? i think it moved left and up
ayyookyndall
  • ayyookyndall
Oh, my bad. Its A
nikato
  • nikato
yup. i would pick that too
nikato
  • nikato
no. you can never use retrice it will never be an answer. just remember no butts. it is because there are too many possibilities. it is ambiguous |dw:1432971832413:dw|
ayyookyndall
  • ayyookyndall
So Im confused?
nikato
  • nikato
those triangles both have two congruent sides and same not included angle. however, they produce two DIFFERENT triangles. just remember you can NEVER use SSA. its "illegal"
nikato
  • nikato
it also has to be D because if you look at all your other answer choice, they involve angles. but you werent given any angle measures, only side lengths

Thank you soooo much!!!! You are amazing!

  • nikato
No problem
