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?
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
Wait, 54 x 4 = 216
Is that it? Thats the answer?
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
So 27 x 4 = 108 108 + 36 = 144
144 is the answer
You simply apply the given rule for each point of the triangle ABC Let me know wat you get ? :)
Whats the rule? Im confused.
(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
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) :)
C moved right and down
are you sure? i think it moved left and up
Oh, my bad. Its A
yup. i would pick that too
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|
So Im confused?
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"
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!
