Abox without a top is made from a rectangular piece of cardboard, with dimensions 12 cm by 10 cm, by cutting out square corners with side length x. which expression can be used to determine the greatest possible volume of the cardboard box? (12−2x)(10−2x)x (12−x)(10−x)x (12x−10)(10x−12) (10−12x)(12−10x)

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
