Not a real number because a negative number is imaginary
Answer:
ok so first we have to do whats in the brackets then we have to do to exponits so first
(-0.00024414062divided by 0.00390625)^2
-0.06249999872^2
-0.00390624984
Hope This Helps!!!
<u>Solid figure</u><u> is also known as flat </u><u>two-dimensional</u><u> shape which only has length and width.</u>
- Geometrically figure , 2-dimensional shapes or objects are flat planar figures with two dimensions—length and width.
- Shapes that are two-dimensional, or 2-D, have only two faces and no thickness.
- Two-dimensional objects include a triangle, circle, rectangle, and square.
What geometric figure is also known as a flat?
- A closed two-dimensional, or flat, figure is called a plane shape.
- Different plane shapes have different attributes, such as the number of sides or corners (or vertices).
- A side is a straight line that makes part of the shape, and a corner, or vertex, is where two sides meet.
What geometric figure is also known as?
Geometric figures are often classified as space figure, plane figure, lines, line segments, rays, and points depending on the dimensions of the figure.

Answer:
49
Step-by-step explanation:
Let be the unknown number. Twice means times 2. So, the mathematical sentence should be .
Divide both sides by 2.
To remove the radical symbol, raise both sides to the second power.
Thus, the answer is 49. Twice the square root of 49 is equal to 14.
