Answer:

-2.4-(-7) has the same result as -2+7 because the negative sign and the minus sign cancel each other out. Think of it like this. If you cross the negative sign and the minus sign together, then it makes a plus sign.

Step-by-step explanation:

I gave a basic answer. You might have to elaborate more on this.

Katyanochek1 [597]
<h2> ☞ANSWER☜</h2>

<h3>3D shapes</h3>
  • Cube Cuboid
  • Sphere Square-based pyramid
  • Cylinder Triangular prism
  • Pentagonal pyramid Hexagonal prism

<h2> ☞EXPLANATION☜</h2>

<em><u>A solid of revolution is a three-dimensional figure obtained by rotating a two-dimensional figure (or curve) around a straight line (called the axis) that lies in the same plane. ... Since the triangle's interior is shaded, it creates the interior of the cone, creating a solid figure.</u></em>

<em><u>Three dimensional shapes are obtained by rotating the two dimensional shapes. When a circle is rotated we get sphere; when a triangle is rotated we get cone; when rectangle or square is rotated we get cylinder</u></em>
