A team has 3 wins for every loss they loss games how many did they win??
OLEGan [10]
The team has lost only 6 games (according to the comments). Let's say "x" is the amount of losses and "y" is the amount of wins.

For every loss, they have 3 wins, so in the end, this would be the equation:
y = 3x
or
y = 3 \times x
Although the first one would be the easier and most understandable to read.

So:
y = 3(6)

Find the volume of the shaded figure by subtracting the smaller volume from the larger
alekssr [168]

Answer:

a. 9a^3 - 9ab^2

b. 9a(a^2 - b^2)

Step-by-step explanation:

a.

Volume = l*w*h

Volume_{smaller} = l*w*h

Where, l = 9a, w = b, h = b

Volume_{smaller} = 9a*b*b = 9ab^2

Volume_{larger} = l*w*h

Where, l = 9a, w = a, h = a

Volume_{smaller} = 9a*a*a = 9a^3

Volume of the shaded figure = 9a^3 - 9ab^2

b. 9a^3 - 9ab^2 expressed in factored form:

Look for the term that is common to 9a³ and 9ab², then take outside the parenthesis.

9a^3 - 9ab^2 = 9a(a^2 - b^2)
