Answer:

Step-by-step explanation:
For the problem:

The Least Common Multiple (LCM) of 3 and 6 is 6. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

Now that the fractions have like denominators, add the numerators:

The Greatest Common Factor (GCF) of 14 and 6 is 2. The result can be simplified by dividing both the numerator and denominator by 2.

7 ÷ 3 = 2R1, therefore:

X^3 -9x+1= 0 (minus 1)
X^3-9x=-1 (divide by 9)
x^3-x=-1/9
But it doesn’t work any further so you have written it wrong
The value of the expression is 4.
We can find this by taking the original equation and plugging in 3 every time we see an x.

Area is a quantity that describes the extent of an area on a plane or curved surface. The area of a planar region or planar region refers to the area of a shape or planar layer, and surface area refers to the area of an open surface or boundary of a three-dimensional object. Wikipedia
The area is the area occupied by a two-dimensional figure. That is, it is a quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is the square unit, commonly expressed in square inches, square feet, and so on.
