Answer:
Step-by-step explanation:
7/15 + 3/5
I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.
Now all we have to do is add the Numerators tog
7/15 + 9/15ether (the top number)
7/15 +9/15 = 16/15 or 1 1/15

So just find the measues of the faces
15 times 4=rightmost face
9 times 4=oposite face
9 times 4=lower top face
to find topmost face
15-9=6
4 times 6=topmost face
sides
can be split up into 2 rectangles
15 by 9 and 6 by 6
2 of them
2 times (15 times 9+6 times 6)
bottom=15 times 4
not seen face=6 times 4
total area=(15 times 4)+(9 times 4)+(9 times 4)+(4 times 6)+(2 times ((15 times 9)+(6 times 6)))+(15 times 4)+(6 times 4)
total area=60+36+36+24+(2 times (135+36))+60+24
total area=60+36+36+24+(2 times 171)+60+24
total area=60+36+60+342+60+24
toal area=582
answer is B
Are those multiplications signs or x variables?
