Factor completely 16x^2+40x+25
Alex17521 [72]

Answer:

Hence, the factor of given algebraic equation:

16x^2+40x+25 is:

(4x+5)^2=(4x+5)(4x+5)

Step-by-step explanation:

<em>" To factor an algebraic equation means to represent it in the most simplest form "</em>

Here we are given an algebraic equation as:

16x^2+40x+25

Now this algebraic equation could also be represented as:

16x^2+40x+25=(4x)^2+2\times (4x)\times 5+5^2\\\\16x^2+40x+25=(4x+5)^2

Hence, the factor of the given algebraic equation:

16x^2+40x+25 is:

(4x+5)^2=(4x+5)(4x+5)

se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m cual es el a
qwelly [4]

Answer:

El área total a pintar será:

A_{tot}=25.2\: m^{2}

Step-by-step explanation:

Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.

El área de un triángulo es:

A_{t1}=\frac{b*a}{2}

b es la longitud de la base (b=3 m)

a es la apotema, osea la altura del triangulo (a = 2.8)

A_{t1}=\frac{2.8*3}{2}

A_{t1}=4.2\: m^{2}

Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.

A_{tot}=25.2\: m^{2}

Espero te haya sido util!

Can someone tell me if this is right thanks
andreyandreev [35.5K]

bearing in mind that an absolute value expression is in effect a piece-wise expression, because it has a ± version.


\bf 3|x|+7=28\implies 3|x|=21\implies |x|=\cfrac{21}{3}\implies |x|=7\implies  \begin{cases} +(x)=7\\ -(x)=7 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ +(x)=7\implies \boxed{x=7}~\hfill  -x=7\implies \boxed{x=-7}

Plz help... geometry volume, density
Ivenika [448]

From what I'm understanding of these questions, the biggest thing you need to answer these is the formulas for cylinders and triangular prisms. I'm not sure what the quantities are for either question so I'm going to work with made up numbers to give examples for the formulas. For number 2 with the cylinder, let's consider the formula first:

π × r2 × h    <em>OR    </em>pi (3.14) times radius squared times height

If you have the height and you have pi, all you need to take is the doubled radius (aka multiply it by 2) and plug that back into the formula. For the sake of an example, I'm going to make up the number 2 for the radius and 6 for the height. Here's what that would look like:

r = 2; double it, resulting in 4

pi x 4^2 x 6

3.14 x 16 x 6

= 301.44

Work with the actual numbers you have and you're good to go.

For number 3, reducing something by 1/2 means dividing by 2. Let's consider the formula and then work through another example:

1/2 x b x h x l   <em>OR </em>   1/2 times base times height times length

For the sake of an example, I'll use 10 for the height, 15 for the base, and 20 for the length:

h = 10; reduce by 1/2, resulting in 5

1/2 x 15 x 5 x 20

= 750

Plug in your actual quantities, and remember your volume units. Hope this helps!
