Using the transitive property of congruence if cd=ef and ef=gh then

The correct option is C. CD = GH

Step-by-step explanation:

We are given in the question that :

CD = EF and EF = GH

we need to use the transitive property of congruence

Transitive Property of Congruence : It states that two objects that are congruent to a third object are also congruent to each other.

Now, CD is congruent to EF and GH is also congruent to EF

So, By using the above transitive property of congruence :

CD must also be congruent to GH

Hence, The complete statement will be : If CD = EF and EF = GH then CD = GH

Therefore, The correct option is C. CD = GH

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
