What geometric figure is also known as flat two-dimensional shape which only has length and width?

Jobisdone [24]

<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.

Find the number such that twice its square root is 14.

NISA [10]

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.

H (t) = -t2 + t + 12 <br> Solve by using quadratic formula

Sedaia [141]

The quadratic formula is:

$x=\frac{-b+\sqrt{(b)^2-4(a)(c)}}{2a}$

and

$x=\frac{-b-\sqrt{(b)^2-4(a)(c)}}{2a}$

Let's identify our a, b, and c values:

a: -1

b: 1

c: 12

Plug in the values for a, b, and c into the equation. Let's do the first equation:

$x=\frac{-1+\sqrt{(1)^2-4(-1)(12)}}{2(-1)}$

Simplify everything in the radical:

$x=\frac{-1+\sqrt{49}}{-2}$

Simplify the radical:

$x=\frac{-1+7}{-2}$

Combine like terms:

$x=\frac{6}{-2}$

Simplify:

$x=-3$

This is one solution, now, let's solve for the other equation:

Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:

$x=\frac{-1-7}{-2}$

Combine like terms:

$x=\frac{-8}{-2}$

Simplify:

$x=4$

Your final answers are:

$x=-3$

$x=4$
