Julio had a job a jeweler. he had the assignment of counting the faces, vertices, and edges on the rubies. on the first ruby, julio counted 30 vertices and 50 edges. he quickly realized he didn't have to count the faces. how many faces were there?

21 faces

23 faces

22 faces

20 faces

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

i’ll just s take the points thxs

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
