3 hours. I think. X represents the # of hours and they equal the same after exactly 3 hours.
Area of a cylinder is computed by the formula: A=2πrh+2πr^2
So the solution will be:
A=2π(2)(5)+2π(2)^2
A=2(3.14)(2)(5)+2(3.14)(2)^2
A=<span>87.96
SO the answer would be 84.96 square units.</span>
Answer : x^7
When you’re multiplying variables like the one in the problem above, instead of actually multiplying, you add. You only multiply in cases where there are coefficients.
Example : z^4 * z^2
Instead of multiplying, you would add the exponents together like so, z^6.
