Answer:
The answer is 125.
Step-by-step explanation:
The formula for volume of a cube is s^3, where s is the length of a side. (Weirdly, you cube a cube.)
So, when you cube 5, the answer is 125.
Let's say make the shapes, some variable name
say
⛁ ⚪ ◽ ▯
a b c d
so.. if take those are the shapes provided
then we can take a look at the first set and we can say that
2a + b + c = 20
a + 4d + b = 19
a + c = 9
3c + d + a = 19
thus

and surely you can find the other two
The answer is 3.3125 because 5÷16=0.3125 and 0.3125+3=3.3125.
this cannot be factored.
there are no 2 numbers that when added will equal - 12 and when multiplied together would equal -36
