Answer:
<h3>AC=96 units.</h3>
Step-by-step explanation:
We are given a parallelogram ABCD with diagonals AC and BD intersect at point E.
, and CE=6x .
<em>Note: The diagonals of a parallelogram intersects at mid-point.</em>
Therefore, AE = EC.
Plugging expressions for AE and EC, we get

Subtracting 6x from both sides, we get


Factoriong quadratic by product sum rule.
We need to find the factors of -16 that add upto -6.
-16 has factors -8 and +2 that add upto -6.
Therefore, factor of
quadratic is (x-8)(x+2)=0
Setting each factor equal to 0 and solve for x.
x-8=0 => x=8
x+2=0 => x=-2.
We can't take x=-2 as it's a negative number.
Therefore, plugging x=8 in EC =6x, we get
EC = 6(8) = 48.
<h3>AC = AE + EC = 48+48 =96 units.</h3>
We have been given two polynomials 
Let us first multiply these polynomials.

Now, we know that polynomials follows closure property of multiplication.
It means that when we multiply two polynomials, the result will be a polynomial.
Since, when we multiplied the given polynomials, we got
which is a polynomial.
Therefore, the correct option is
The result
is a polynomial.
The estimate of 299 is 300.
The estimate of 388 is 400.
So, 300 + 400 = 700
We are given with
<span>E (0, 27)
</span><span>F (5,−8)
and we are asked to get the rate of change and the initial value:
To get the rate of change, we simply have to use the slope formula:
m = (-8 - 27) / (5 - 0) = -7
The rate of change is -7
The initial value is the value of y when x is 0 which is the coordinates of E. So, the initial value is 27.</span>
