1) a∠12 because this sign means you must be less than 12 years old as a stands for age maybe.
2) it's the 3rd one because always remember that a closed circle is for ≤ or ≥
so now you've to choose between the last two.. always remember if the sign directs right the graph is left and vice versa..Hope this helps:)

3) There are 12 inches in a foot, so 144/12 equals 12 feet- the distance above the floor. 12 goes into 40 about 3 times. 3 feet + 12 feet equals about 15 feet.

4) When you want to find the percentage of something, you would take the percentage and move the decimal place two spaces to the left. So 45% becomes .45. Then you would multiply that by the number of houses. .45 times 36 equals 16.2. Rounded to the nearest whole number, 16 houses display holiday lighting.

What is the sum of 2 / 3x^2 +12x and 8 / c. Need steps

Marta_Voda [28]

Answer:

$\frac{2c}{3x^2c}+ \frac{36x^3c}{3x^2c} +\frac{24x^2}{3x^2c} [\tex]Step-by-step explanation:We need to find sum of 2 / 3x^2 +12x and 8 / cSo, solving:[tex](\frac{2}{3x^2} + 12 x ) +\frac{8}{c}$

Taking LCM of 3x^2 and 1 i.e. 3x^2

$=(\frac{2 + 12 x(3x^2)}{3x^2} ) +\frac{8}{c}\\=(\frac{2 + 36x^3}{3x^2} ) +\frac{8}{c}\\=\frac{2 + 36x^3}{3x^2} +\frac{8}{c}\\LCM \,\, 36x^2 c\\=\frac{(2 + 36x^3)c + 8(3x^2)}{3x^2c}\\=\frac{2c + 36x^3c + 24x^2}{3x^2c}\\= \frac{2c}{3x^2c}+ \frac{36x^3c}{3x^2c} +\frac{24x^2}{3x^2c}$
