How do you factor 7X cubed 49X squared plus 84X?

To factor the expression ( 7X^3 + 49X^2 + 84X ), first, identify the greatest common factor (GCF) of the terms, which is ( 7X ). Factoring out ( 7X ) gives ( 7X(X^2 + 7X + 12) ). Next, you can further factor the quadratic ( X^2 + 7X + 12 ) into ( (X + 3)(X + 4) ). Thus, the fully factored form is ( 7X(X + 3)(X + 4) ).


What is the LCM of 7x and 12x?

Since x is a factor of both numbers, ignore it and find the LCM of 7 & 12. These two numbers do not share any factors, so their LCM is 7*12 = 84. Put the x back in for the final answer - 84x.

What is the area of a square that has a side of 6x 7?

Thanks to limitations of the browser used for posting questions, it is not possible to tell whether the sides are 6x - 7 units or 6x + 7 units. For 6x - 7 units, area = 36x2 - 84x + 49 square units. For 6x + 7 units, area = 36x2 + 84x + 49 square units.


Solve for x in the following 3 over14 equals 84?

In order to solve for x, there must be an x in the equation.If you meant to say 3x/14=84, then 3x=14(84), so x=392 If you meant to say 3/14x=84, then 84x=3/14, so x=0.00255102041 If you meant to say 3/14=84x, then the above line is the answer.
