Step-by-step explanation:

Similar shapes may or may not be congruent.
The value of x is (a) 9.0
The corresponding sides are:
- AB and DE
- BC and EF
- AC and DF

Because the shapes are congruent, and AC corresponds to DF.
This means that:

So, we have:

Collect like terms


Divide both sides by 5

<em>Hence, the correct option is (a) 9.0</em>

Answer:
Step-by-step explanation:
10x^3 + 35x^2 - 4x - 14
5x^2(2x + 7) - 2(2x + 7)
