Which of the following is NOT true about unit rates? 1. A unit rate relates a quantity to

2. Unit rates can be used to compare two rates.

3. Any rate is equivalent to its unit rate.

4. A unit rate always relates quantities with the same units.

1,2,3,4 is the correct option

4

Step-by-step explanation:

For different problems or situations, the unit might be different (dollars, miles, crocodiles, etc). However, a unit rate can be used to compare two rates and is always equal to any other rate you can write for the same problem. (since 4 is clearly false, I assume 1 is correct, even though it seems to have been cut off).

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
