X is minus 30 over 7
So you can cross multiply and multiply the values.
Then you can solve it like a normal equation
Answer:
w=7.1
Step-by-step explanation:
The length of the AC is x^2 + 4x - 12.
<h3>What is a parallelogram?</h3>
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given :
In Parallelogram ABCD, diagonals AC and BD intersect at point E.
such that
AE = x^2 - 12,
CE = 4x
We know that the diagonal of a parallelogram bisect each other.
x^2 - 12 = 4x
x^2 - 4x - 12= 0
(x-6)(x-2) = 0
Hence, the value of x = 6, 2.
AC = AE + CE = x^2 + 4x - 12.
The length of the AC is x^2 + 4x - 12.

______________________________
<h3>
1.) Find the LCF of 6 and 4:
</h3>
<em> - We do this because in order to add these, they must have the same denominator. So you must find the LCF, (Least Common Factor) of 6 and 4.</em>
<em />
<h3>
2.) Convert the fractions to have the same denominator:
</h3>
<em> - </em>
<em> changes to </em>
<em> by multiplying the numerator and denominator by 2. And </em>
<em> changes to </em>
<em> because you multiply the numerator and denominator by 3. </em>
<em></em>
<h3>
3.) Add the numerators:
</h3>
<em> - Since both fractions have the same denominator all you have to do is add the numerators together. </em>
