Answer:

x= 15 so the c) is right

Step-by-step explanation:

We can do it like:

3(2x + 5) = 3x + 4x

or 6x + 15 = 7x

-6x+ 6x +15 = -6x+ 7x

or 15 = x

The solution is 15

Hope you understand it.

lina2011 [118]

Answer:

46656 to the power 4

Step-by-step explanation:

6 to the power 6 = 6 × 6 × 6 × 6 × 6 × 6 = 46656

(46656) to the power 4 = 46656 × 46656 × 46656 × 46656

This answer is undefined, so we will leave it at 46656 to the power 4.
