40000 mg = 10x g. what is value of x

Serjik [45]

Given:
40,000 mg = 10x g

1 gram is equal to 1000 milligram

40,000 mg * 1 gram/1,000 mg = 40,000 g / 1,000 = 40 gram

40 grams = 10x g
40 grams / 10 grams = x
4 = x

The value of x is 4.

40000 mg = 10x g
40000 mg = 10(4) g
40000 mg = 40 g

Expand and simplify (2x−12) ^2

lubasha [3.4K]

Answer:

$\boxed{4x^{2} - 48x + 144}$

Step-by-step explanation:

Given expression:

(2x - 12)²

To simplify the expression, we will use the formula (a - b)² = a² - 2ab + b².

[Where "a and b" are the first and second term in (a - b)²]

$\rightarrowtail (2x - 12)^{2}$

In this case, the first term of (2x - 12)² is "2x" and the second term is "12".

$\rightarrowtail (2x)^{2} - 2(2x)(12) + (12)^{2} \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\small\text{First term = a = 2x; Second term = b = 12]}$

Now, simplify the expression.

$\rightarrowtail (2x)^{2} - 2(2x)(12) + (12)^{2}$

$\rightarrowtail (2x)(2x) - (4x)(12) + (12)(12)$

$\rightarrowtail \boxed{4x^{2} - 48x + 144}$
