Answer:

<em>Option C; Option D; Option E</em>

Step-by-step explanation:

<em>~ The volume of this prism is calculated through the general Base * height formula, in other words length * width * height ~</em>

Here the length ⇒ 2x + 5, the width serves as ⇒ 2x- 5, and the height ⇒ 3x

1. Knowing the dimensions, let us apply the formula length * width * height to substitute and simplify to the point: ( 2x + 5 ) * ( 2x - 5 ) * ( 3x )

2. Through the process of simplification, we derive the answer ( s ):

( 2x + 5 ) * ( 2x - 5 ) * ( 3x ) =                                     3x * ( 4x^2 - 25 )  =

( 3x ) * ( 2x )^2 - ( 5 )^2 =                                        <em>12x^3 - 75x; Option C</em>

<em>3x  * ( 4x^2 - 25 ); Option D </em>

              or                                                ⇒      ( 2x + 5 ) * ( 6x^2 - 15x )   =

( 2x + 5 ) * ( 2x - 5 ) * ( 3x ) =                                 <em>12x^2 - 75x; Option C</em>

<em>( 2x + 5 ) * ( 6x^2 - 15x ); Option E</em>

<em>               </em>

It takes 9 builders 54 days to complete a house.
Dima020 [189]

It would take 6 builders  36 days to complete the same house.

<h3>Who are builders?</h3>

Builders are those person whose job is to build or repair houses and other buildings.

We have,

9 builders take 54 days to complete a house.

So,

1  builder will take  (\frac{54}{9})  days to complete a house,

In the same way,

6  builder will take  (\frac{54}{9}*6)  days to complete a house,

i.e.

6  builder   =(\frac{54}{9}*6)= 36 days.

Hence, we can say that it would take 6 builders  36 days to complete the same house.

When Vince does 14 push-ups and 12 sit-ups, it takes a total of 52 seconds. In comparison, he needs 48 seconds to do 12 push-ups
marshall27 [118]

Answer:

it takes 2 seconds to do one situp

it takes 2 seconds to do one pushup

to do 14 pushups, it takes 28 seconds.

to do 12 situps it takes 24 seconds

to do 12 pushups, it takes 24 seconds

BRAINLIEST PLEASE!

hope this helps :)

Step-by-step explanation:

14x + 12y = 52

12x + 12y = 48

^^^ this is an inequality that we can make.  

x stands for pushups

y stands for situps

if we subtract the second equation from the first, we get

2x = 4

x = 2

now we can place x in one of the equations to solve for y

12(2)+12y=48

24 + 12y = 48

12y = 24

y = 2
