<p>The second is no solution. You can simply input all the answer choices in place of X one at a time. See if the two sides match up. You will see in all cases they will not. U will get a math error on most bcuz of the negative square root</p>
<p>Yeah, the answer to the first question is “cone.” The bottom leg of the triangle spins around and forms a circle, and that circle is the circular case of the cone. The hypotenuse spins too, and both hypotenuses connect to the ends of the circular base. The vertical leg stays still. And idk, the exact same question was one of my geometry test questions and I recall getting this answer correctly. </p>
<p>And for the second problem, I actually think the answer is D (8). If you plug 8 for x, they both equal out to -25.</p>
