You said . . . -12√12 - 2√3 .
Before we get all tangled up trying to work on the whole thing at once,
take a look at that first square root: √12 .
That's the same thing as √(4 · 3) and you can break it up like this:
√(4 · 3) = √4 · √3 .
Now, we know what √4 is . . . it's just 2 .
So we can write the first half of your original big quantity like this:
-12 √12
= -12 · 2 · √3
= -24√3 .
NOW, finally, let's go back and rewrite the whole thing:
-24√3 - 2√3 .
Isn't that a lot nicer looking ?
It's nearly solved all by itself ... if you don't let the √3 scare you.
It just says -24(cows) - 2(cows) .
and everybody knows, that's just -26(cows).
So -24√3 - 2√3 is just -26√3 . (choice-C)

EXPLANATION
The given quadratic functions are;
and
A fractional coefficient indicates a horizontal stretch.
The smaller the coefficient, the wider the stretch for
and
Also
indicates a horizontal compression.
The higher the value the narrower the graph.
Therefore from widest to narrowest, we have,

Jana could have bought any number greater than 3.5 because 3.5 is the middle of 3-4. If the amount of trail mix is closer to 4 pounds, the pounds she could have bought must be greater than 3.5 but less than 4 pounds.
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
Answer:
$1798
Step-by-step explanation:
You take the money of 1550 and multiply the 16% for the 2 years, which is just 1.16 and you get 1798
