The correct answer is A. D
That is because D has a horizontal line of symmetry, as can be seen on it.
Solve for R by simplifying both sides of the equation, the isolating the variable.
R^2h=-r^2+v
When a number with an exponent is raised to an exponent, you multiply the two exponents together to get the combined exponent of the simplified version.
Let's take our exponents, 2 and 3, and multiply them.
2 x 3 = 6
Therefore we can apply the sixth power to 3a for our final answer of 3a⁶.
Hope this helped!
