64^x=16^x-1====> Make the bases the same
4^3(x)=4^2(x-1)=> Solve for x by bringing down the exponent without the base.
3(x)=2(x-1)=====> Distribute
3x=2x-2======> Now solve for x
3x = 2x-2
-2x -2x
x=-2
Therefore x is negative two
Area of a circle=πr²
r=radius=13 cm
area of a circle=π(13 cm)²=169π cm²≈530.93 cm²≈530.7 cm²
Answer: B.530.7 cm²
Answer:
First option is correct answer.
Step-by-step explanation:
Area = 4x - 10
Perimeter = x + 8
The answer is C. All you need to do is find the Y values that correspond with the X values. Have a great day
I think answer is b that is 10raise to 2
