Answer:
x = 7
Step-by-step explanation:
The dashes on the lines show they are equal in length.
Therefore, by inspection of the diagram, we can see that the measures of the sides of the smaller triangle (with base 5x) are half the measures of the sides of the larger triangle (with base 70).
Therefore, creating an equation with this information:
5x = 1/2 x 70
⇒ 5x = 35
⇒ x = 7
The answers are A,B, and E. Hope this helps. :)

Lets get started :)
Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.
When multiplication occurs in the same base, we add the powers

↓ (I am going to perform the problem separately and then give the final answer as the power to x)

=

↓
x²

The power of a power should be performed by multiplying the powers together.
2 x

=


Your final answer will be the second option
