\implies {\blue {\boxed {\boxed {\purple {\sf { \: x =  - 6}}}}}}

\sf \bf {\boxed {\mathbb {Step-by-step\:explanation:}}}

\:8 + 4x =  - 16

➺\: 4x =  - 16 - 8

➺\: 4x =  - 24

➺\: x =  \frac{ - 24}{4}

➺\: x =  - 6

\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}

\:8 + 4x =  - 16

➼\: 8 + 4( - 6) =  - 16

➼\: 8 - 24 =  - 16

➼\:  - 16 =  - 16

➼\: L.H.S.=R. H. S

Hence verified.

The solution to the problem and how would I work it out?
Zinaida [17]

Answer:

x >=5  or x <=-3

Step-by-step explanation:

Solve an absolute value inequality

3|x-1| >= 12

Divide each side by 3

3/3|x-1| >= 12/3

|x-1| >= 4

Now there are two solutions

x-1 >= 4   or x-1 <= -4

Add 1 to each side

x-1+1 >= 4+1   or  x-1+1 <= -4+1

x >=5  or x <=-3

The right rectangular prism is made up of 48 cubes. Each cube has an edge length of inch. What is the volume of this prism?
Gnesinka [82]

Given:

  • The right rectangular prism is made up of 48 cubes.
  • Each cube has an edge length of 1/4 inch.

~

To Find:

  • What is the volume of this prism?

~

Solution:

~

<u>Using formula: </u>

~

  • \sf \pmb {Volume  \: of \:  cube =  {(side)}^{3} }

~

Substituting values in the formula:

~

\sf \longrightarrow  \dfrac{1}{4}  \times  \dfrac{1}{4}  \times  \dfrac{1}{4}

\sf \longrightarrow \dfrac{1}{64}  \:  {inch}^{3}

~

Now,

Volume of 48 such cubes = Volume of 1 cube × 48 cubes

~

\sf \longrightarrow \dfrac{1}{64}  \times 48

\sf \longrightarrow \dfrac{48}{64}

\sf \longrightarrow \dfrac{3}{4}  \:  {inch}^{3}

~

Hence,

  • Volume of prism is <u>3/4 inch^3</u>
