Which explains whether or not this model accurately shows 13 × 3?
it does because 13 = 10 + 3, and the model shows 3 groups of 10 and 1 group of 3.
it does because 13 = 10 + 3, and the model shows 3 groups of 10 and 3 groups of 1.
it does not because 13 = 10 + 3, and the model should show 1 group of 10 and one
group of 3.
it does not because 13 = 10 + 3, and the model should show 3 groups of 10 and 3
groups of 3.

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
