Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

Let's first establish that the shape is a triangle meaning that the following formula is applicable as displayed below:

Angle sum of a triangle = 180°

As well as this, the shape is an equilateral triangle meaning that each angle of the triangle is equivalent in value. Also, the following formula is also applicable as displayed below:

Each angle of an equilateral triangle = the same value

Therefore:

Each angle of an equilateral triangle = angle sum of a triangle ÷ no. of angles in a triangle = 180° ÷ 3 = 60°

Based on this, the following is applicable:

2x - 4 = 60°

2x = 60 + 4

2x = 64

x = 64 / 2

x = 32°

ANSWER:

Therefore, the answer is:

The value of ( x ) is 32°

Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly? x = StartFraction negative

AnnZ [28]

Answer:

$x=\frac{9+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}$

Step-by-step explanation:

Recall that the quadratic formula gives you the pattern to follow in order to find the solutions to a quadratic equation of the form: $ax^2+bx+c=0$

It tells us that we need to use the parameters $a,\, b,$ and $c$ in the following formula in order to get the answers for the x-values that solve it:

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

so, in our case, $a=1$ , $b=-9$ , and $c=-20$

then, replacing these values in the formula, we obtain:

$x=\frac{-b+/-\sqrt{b^2-4\,a\,c} }{2\,a}\\x=\frac{-(-9)+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}\\x=\frac{9+/-\sqrt{(-9)^2-4\,(1)\,(-20)} }{2\,(1)}$

Which looks like the third expression you are listing (although it is a little hard to read)

Select all the shapes below that have a constant cross-section between a

meriva

The shapes below that have a constant cross-section between a pair of faces are cylinder, cube, sphere, hexagonal, and prism.

<h3>What is the definition of geometry?</h3>

It is concerned with the geometry, region, and density of various 2D and 3D shapes.

A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.

The shapes have a constant cross-section between a pair of faces like a cylinder.

Hence,cylinder, cube, sphere, hexagonal, and prism are the forms below that have a constant cross-section between a pair of faces.
