Answers

Answer:

-8 (4 x^2 - x + 1)

Step-by-step explanation:

Simplify the following:

3 x (x - 12 x) + 3 x^2 - 2 (x - 2)^2

x - 12 x = -11 x:

3 x×-11 x + 3 x^2 - 2 (x - 2)^2

3 x (-11) x = 3 x^2 (-11):

-11×3 x^2 + 3 x^2 - 2 (x - 2)^2

3 (-11) = -33:

-33 x^2 + 3 x^2 - 2 (x - 2)^2

3 x^2 - 33 x^2 = -30 x^2:

-30 x^2 - 2 (x - 2)^2

(x - 2) (x - 2) = (x) (x) + (x) (-2) + (-2) (x) + (-2) (-2) = x^2 - 2 x - 2 x + 4 = x^2 - 4 x + 4:

-30 x^2 - 2 x^2 - 4 x + 4

-2 (x^2 - 4 x + 4) = -2 x^2 + 8 x - 8:

-2 x^2 + 8 x - 8 - 30 x^2

Grouping like terms, -2 x^2 - 30 x^2 + 8 x - 8 = (-30 x^2 - 2 x^2) + 8 x - 8:

(-30 x^2 - 2 x^2) + 8 x - 8

-30 x^2 - 2 x^2 = -32 x^2:

-32 x^2 + 8 x - 8

Factor -8 out of -32 x^2 + 8 x - 8:

Answer: -8 (4 x^2 - x + 1)

How much is a milliliter

Answers

-- 236 of them make 1 cup
-- 946 of them make 1 quart
-- the volume of a tiny cube that's 1 centimeter along each edge
-- 16.4 of them in a little cube that's 1 inch along
-- 4.9 of them make a standard cooking teaspoon
-- a perfume that cost $50 an ounce would cost $1.69 per milliliter

If you mean by 'How much is a milliliter to a litre'
It would be equivalent to:
1 milliliter = 0.001 litres

What is the solution to the equation?3q + 5 = –2q + 20 A. q = 3 B. q = 5 C. q = 15 D. q = 25

Answers

$3q + 5 = -2q + 20$

add 2q to both sides.

$5q + 5 = 20$

subtract 5 to both sides.

$5q = 15$

divide 5 to both sides.

$q = (15)/(5)$

the answer is: $q = 3$
