Answer:
C, 108
Step-by-step explanation:
rectangles
8x3 = 24
8x4 = 32
8x5 = 40
triangles
3x4 = 12
you dont really have to divide by 2 since theres two triangles
24+32+40+12 = 108
The prime factors of 15 are: 1,3,5,15
The prime factors of 21 are: 1,3,7,21
The prime factors of 38 are: 1,3,13,39
The prime factor of 42 is : 1,2,3,6,7,14,21,42
5
G.C.F means greatest common factor
this means the highest number that will go into both 25 and 40
5 is the highest number that will divide into both
it's ¢.34
a gallon has 16 cups
since there are two gallons that's 32
the price of the two gallons divided my 32 is how much each cup would be so 10.88/32 would be ¢.34
29=b
30=a
