4(2x^2 + 17x + 21) This reduces the size of the numbers you need to try.
It's going to look like this when you factor
4(2x + ___) (x + ___)
Now its a guessing game.  Start with 7
4(2x + 7)(x + 3) you need the 3 to multiply to 21
But the middle term when you expand this is 7x + 6x = 13x which does not work. Try switching the 7 and 3.

4(2x + 3)(x + 7)
This your answer. because 3x + 14x = 17x.

steposvetlana [31]
1/2 + 2x = (3+4+12)x / 12

1/2 + 2x = 19x/12
1/2 = -5/2 x

x = -1/5

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?
Oduvanchick [21]
Remember that (g-f)(x) is g(x)-f(x). We know form our problem that f(x)=4-x^2 and g(x)=6x, so:
(g-f)(x)=g(x)-f(x)
(g-f)(x)=6x-(4-x^2)
(g-f)(x)=6x-4+x^2

Now, to find (g-f)(3), we just need to evaluate (g-f)(x) at 3. In other words, we are going to replace x with 3:
(g-f)(x)=6x-4+x^2
(g-f)(x)=6(3)-4+(3)^2

We can conclude that the correct answer is <span>C.6(3) – 4 + 3^2 </span>

Use the conversion table to convert the following English units into the given metric units. Calculate all problems by hand. Rou
Gala2k [10]

10 in × 25.4 = 254 millimeters

60 ft × 0.3048 = 18.29 meters

4.5 in × 25.4 = 114.3 millimeters

12 US Quarts × 0.946 = 11.35 liters

25 ft/sec × 0.3048 = 7.62 meters

100 miles × 1.609 = 160.9 kilometers

<em>NOTE: Next time, please attach the conversion table to ensure we are using the table referenced in the question.</em>
