To solve for x, you need to isolate/get the variable "x" by itself in the inequality:

12x + 7 < -11 Subtract 7 on both sides

12x + 7 - 7 < -11 - 7

12x < -18 Divide 12 on both sides to get "x" by itself

$\frac{12x}{12}$

$x$ Simplify the fraction

$x$ (x is any number less than -3/2)

Answer: b = p - a -c

Step-by-step explanation:

p= a + b + c Solving for b means getting b on one side by itself.

p = a + b + c To solve for b first subtract a from both sides to get,

-b -b

p - a = b + c Now subtract c from both sides to get

-c -c

p - a - c = b

b = p - a -c

The volume of a rectangular prism is 6x^3 -x^2 -2x. Which model could represent the rectangular prism?

Oksi-84 [34.3K]

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

l - length

w - width

h - height

We have the volume:

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

The measure of x in both parts is: 120°

Step-by-step explanation:

Part A:

We can clearly see that the figure in part a has six equal sides. So the given figure is a hexagon.

A hexagon has six equal sides in six equal interior angles.

Sum of interior angles of hexagon is 720°

So,

$Measure\ of\ one\ agnle=\frac{Sum\ of\ interior\ angles}{number\ of\ angles}\\=\frac{720}{6}\\=120$

Part B:

The figure is a Dodecagon with 12 sides.

The Dodecagon has 12 equal sides and angles.

The sum of internal angles of Dodecagon is 1440°

So,

$Measure\ of\ one\ angle=\frac{Sum\ of\ angles}{Number\ of\ angles}\\=\frac{1440}{12}\\=120$

The measure of x in both parts is: 120°
