Answer:
4 r^3
Step-by-step explanation:
sqrt ( 16 r^6 ) = sqrt ( 4^2 * (r^3)^2 ) = 4 r^3
Answer:
The second number after the decimal point- the 6
You're answer will be C 13x2+12xy+9y2
Answer:
The first answer and the second answer.

The slope perpendicular to 1/4 or .25 is 4.
Then you would use point slope form to write the equation.
Then you could simiplify the equation to y=4x+32.
