Seven less than 4 times the square of a number is 18. Find the two numbers.
The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Answer:
Triangle ADB is congruent to triangle DBC
Step-by-step explanation:
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.
Si en un grupo de 10 personas se va a repartir refrescos de 10 sabores diferentes, y se sabe que hay uno de fresa y uno de piña ¿cuál es la probabilidad que el primero en ser repartido sea de piña y el segundo de fresa?
Respuesta: 0.011
Explicación paso a paso:
Dado que:
Número de sabor a refresco = 10
Número de sabor a piña = 1
Número de sabor a fresa = 1
P (primero es fresa) = número de sabor a fresa / número total de sabor
P (primero es fresa) = 1/10
P (el segundo es sabor a piña) = número de sabor a piña / número total de sabor
P (segundo sabor a piña) = 1/9
Probabilidades independientes:
P (primero es fresa) * P (segundo sabor a piña)
= (1/10) * (1/9)
= 1/90
= 0.011

The vertices of an ellipse are (0,-1) and (8,-1). The endpoints of the minor axis are (4,1) and (4,-3). Write the equation of the ellipse in general form
Answer:
x^2+4y^2-8x+8y+4=0
Step-by-step explanation:
The general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.
What is an ellipse?An ellipse can be defined as a shape that looks like an oval circle.
The equation of an ellipse is
[tex]\dfrac{\left(x - h\right)^{2}}{a^{2}} + \dfrac{\left(y - k\right)^{2}}{b^{2}} = 1[/tex]
Where (h, k) is the center a and b are the lengths of the semi-major and the semi-minor axes.
The vertices of an ellipse are (0,-1) and (8,-1).
The endpoints of the minor axis are (4,1) and (4,-3).
The following equations take into account the different properties of an ellipse:
[tex]k = -1k=−1, h^{2} = a^{2}h 2 =a 2 , \left(h - 8\right)^{2} = a^{2}[/tex]
[tex]\begin{cases} b = 2 \\ k = -1 \\ h^{2} = a^{2} \\ \left(h - 8\right)^{2} = a^{2} \end{cases}[/tex]
We get that h = 4 k = -1, a = 4, and b = 2
The standard form of the given ellipse is
[tex]\dfrac{\left(x - 4\right)^{2}}{4^{2}} + \dfrac{\left(y + 1\right)^{2}}{2^{2}} = 1[/tex]
So the general form will be as : x² +4y² - 8x + 8y + 4 = 0.
Thus, the general form of the given ellipse is x² +4y² - 8x + 8y + 4 = 0.

The length of a rectangle is 6 cm more than twice its width. The sum of the length and width is 24 cm What are the dimensions of the rectangle?
Enter your answers in the box.
Answer:
width:6, length:18
Step-by-step explanation:
You can subsititue width with x.
The length would then be 2x+6.
The value of width and length combined is 24.
The equation would be (2x+6)+(x)=24
Simplify to 3x+6=24
Subtract 6 from both sides giving 3x=18
Simplify to x=6
There's the width. Now you can substitute to find the length.
(6x2)+6=18
I hope this is right.
