The formula of a volume of a rectangular prism: V = lwh

l - length

w - width

h - height

We have the volume:

$V=6x^3-x^2-2x=x(6x^2-x-2)=x(6x^2+3x-4x-2)\\\\=x[3x(2x+1)-2(2x+1)]=x(2x+1)(3x-2)\\\\Answer:\ \boxed{A.\ Height:3x-2,\ Length:2x+1,\ Width:x}$

A student's cost for last semester at her community college was $2900. She spent $406 of that on books. What percent of last

sweet [91]

We can get the percent by taking 406 / 2900 as a decimal, then multiplying by 100. 406 / 2900 is 0.14, then multiplied by 100 is 14%.

No pude entender tu pregunta. Pienso que estás buscando la cantidad de metros en 3km 312m.
3km = 3,000m.
3,000m + 312m = 3,312m.

3. A fire truck is parked twelve feet

Firlakuza [10]

Answer: 9.04 feet

Step-by-step explanation:

First, it is important to draw a Right triangle, as the one attached, where "x" represents the height in feet from the ground in which the fire is burning.

In this case you need to use the following Trigonometric Identity:

$tan\alpha =\frac{opposite}{adjacent}$

You can identify that:

$\alpha=37\°\\\\ opposite=x\\\\adjacent=12$

Therefore, you can substitute values into $tan\alpha =\frac{opposite}{adjacent}$ :

$tan(37\°)=\frac{x}{12}$

Finally, you must solve for "x" in order to find its value. You get that this is:

$12*tan(37\°)=x\\\\x=9.04$

How do u do number 18? helppppppp

DanielleElmas [232]

360° (a circle) = 2pi radians, so 720×2pi/360
= 2×2pi = 4pi
4pi = a*pi
a = 4
