You don’t know because they don’t say how many friends there are with marbles.
The answer will be a because they are similar and by law the ratio can be cubed to find ratio of volume
For this case we must find the quotient of the following expression:

We can rewrite the expression as:
(We take into account that
)

By definition of multiplication of powers of the same base, we place the same base and add the exponents:

By definition of division of powers of the same base, we place the same base and subtract the exponents:

Answer:

Answer:
0.5 repeating
Step-by-step explanation:
you would simply divide 5 by 9 to find the answer.
Answer:
7x2 + 14x = 0
x2 + 3x -5 = 0
x2 - x = 3x + 7
Step-by-step explanation:
A quadratic equation has the highest power of x to the second power. It must have x to the second power
7x2 + 14x = 0 quadratic
x3 - 3x2 + 1 = 0 not quadratic but cubic
5x - 7 = 0 not quadratic but linear
x2 + 3x -5 = 0 quadratic
x - 5 = 9x + 7 not quadratic but linear
x2 - x = 3x + 7 quadratic
