x=-2

Step-by-step explanation:

1. Convert base

(1/64) to (4^-3)

2.Apply exponent rule

4^-3(2x+10)

3. 4x-10=-3(2x+10)

4.Expand

4x-10=-6x-30

4x-10+10=-6x-30+10 (add 10 to both sides)

4x=-6x-20 (simplify)

4x+6x=-6x-20+6x (add 6 to both sides)

5. 10x=-20 (divide both side by 10)

6. Then you get x= -2.

17.32

Step-by-step explanation:

1. The distance of O x-axis to P x-axis is 12

2. The distance of P y-axis to P y-axis is 16

3. Apply Pythagorean theorem √(12^2 +16^2)
