Factor
solmaris [256]

The correct answer is C) (5m^50 - 11n^8) (5m^50 + 11n^8)

We can tell this because of the rule regarding factoring the difference of two perfect squares. When we have two squares being multiplied, we can use the following rule.

a^2 - b^2 = (a - b)(a + b)

In this case, or first term is 25m^100. So we can solve that by setting it equal to a^2.

a^2 = 25m^100 -----> take the square root of both sides

a = 5m^50

Then we can do the same for the b term.

b^2 = 121n^16 ----->take the square root of both sides

b = 11n^8

Now we can use both in the equation already given

(a - b)(a + b)

(5m^50 - 11n^16)(5m^50 + 11n^16)

If f(x) = 3x +9 x when f(x) = 30
den301095 [7]

Answer:

x=5/2

Step-by-step explanation:

When f(x)=30, we have 3x+9x=30.

Combining like terms on the right side, we have 12x=30.

Finally, dividing by 12 we get x=30/12.

We note that 30=6*5 and 12=6*2, so 30/12=5/2.

So, \boxed{x=5/2} and we're done!
